5510 Air Purifier (New Generation of 5500-2 with App Support) for Home Large Room Up to 1881 Ft² in 1 Hr, True HEPA, High Deodorization Carbon Filter and Auto Mode, Captures Pet Allergies, Smoke

I really like this purifier. It works well for pets. I Have rinsed and wiped the first filter several times and the inner filters still are clean. 3 dogs and two people in the home. On high it blows a lot of air. On the next level 3 it works perfectly. Not too loud but very effective. It helps with pet allergies and stops the sneezing and watery eyes. It definitely removes dander, dust, and other allergens well.

A really good air purifier with some unique features. In terms of noise, it is among the quietest at about 60 DB. Obviously there’s more noise the faster the fan spins, but in automatic mode, it senses the amount of gluten in the air and adjust the speed automatically which means most of the time it will be running at low speed unless there’s a lot of dust in the air. You can download an android or iOS app to control the fan speed and to see how much dust it is seeing in the air. You can also set it up for Alexa or Google Home to be able to control it through those devices. One need feature is being able to ask Alexa for a reading of air quality from the device. You can also enable an automatic sleep mode, which basically keeps the device on auto fan mode where it senses the amount of dust in the air during daylight, but when the device notices that the room is dark at night, it will put the fan speed to its slowest mode to ensure that there’s minimal noise during nighttime hours. Once the room is lit again and it is daylight the device will automatically switch to auto mode and if necessary, increase the fan speed to pull in more air if it detects an increased amount of dust. These are the main features of the device, but the other thing that I liked about it compared to similar models from other brands is that they say the standard filters it comes with should last 12 months where many other brands recommend changing filters after three months. This is probably because the HEPA filter that this device comes with is thicker at about 1 inch compared to what I have on other air purifiers filters that are generally 1/2 inch or less thick. I have not yet replaced my filters, but with an estimate of one year it should not be a substantial yearly cost because filter filters run around $20. And I say filters because as you can see in the images for the product, there are actually two separate filters that work together one is a white HEPA filter to filter out particles. The other one is a black carbon filter, which filter filters out smell smells. And holding both of those filters in place is a screen which is washable that is meant to capture, larger dust particles or pet hair before they hit the main filter filters. Overall, very satisfied with this device and the only thing I can’t really comment on is how long it will last as I’ve only recently started using it.

We've had one heck of a fire season this year--and if you live in the Western United States, I can already see you nodding your head in agreement. That's probably why you're here reading this review. Thank goodness for air purifiers. Chances are you've already looked at tons of them. You might even be confused as to which one to choose. Hopefully I can help you out with that. In essence, all an air purifier has to do is filter the air and expel it in better shape than it inhaled it. Most units (including the Winix unit here) do this by pulling the air through a HEPA filter--and that certainly helps. If all you're looking to do is reduce dust, you can stop here. Pick a filter, any filter. You'll get the job done. But why stop with one layer of filtration when this unit offers you four? When the air enters your Winix, it will first encounter a cleanable dust screen. This screen is much like what you may have in front of your computer case fans. Large particles get stuck here rather than in your HEPA filter, meaning you won’t have to replace the HEPA as often. In fact, Winix recommends replacing the HEPA once a year; you may have noticed that other brands recommend changing filters every three months or so. That’s why, and it serves as Layer One. The next layer is a honeycomb filter which is filled with activated carbon. You see, HEPA filters alone won't eliminate odors. Just like how activated carbon will remove odors from fish tanks when used as part of the tank's filtration, it also removes odors from the air. Pet dander, wildfire smoke, a certain someone’s love of gassy foods… yeah, you’ll like this function. That’s Layer Two. Layer Three is the HEPA filter itself. Small particles you may not be able to see--but will still do a number on your eyes and sinuses--get stopped in their tracks here. Layer Four is a negative-ion filter that Winix calls “Plasmawave.” Without over complicating the science behind it, this feature will make it harder for viruses to spread and will cause smaller particles to sink where they can be collected easier. This feature can be turned off if you don’t see the need for such thoroughness or perhaps you’re skeptical of the process, but I strongly suggest leaving it on. When it’s time to change (or clean, in the case of your dust screen) your filters, getting to them is easy. The entire front panel is held on by magnets (better than plastic tabs which can break over time). The filters themselves are easy to find right here on Amazon, and they are reasonably priced. You’ll be switched over in minutes. Your biggest hassle just might be tearing your new filters out of its packaging. Now let’s talk about features. For the vast majority of the people, simply hitting the “auto” button will work. This unit has an air quality sensor, and it will automatically increase its fan speed when it senses that your air quality has declined. Once air quality improves, it’ll slow down its fans. It’s a set-and-forget type of thing. For those who are more hands-on, you can bypass the auto mode and choose your own fan speed. This is useful if you’re running this unit in a room that needs more “reach,” or if you find the white noise of the fans to be soothing. On maximum speed, the unit is still quiet enough to hold a conversation next to it—a box fan is far, far louder. The filtered air is pushed upward, where it can more easily circulate in the room without diluting the denser polluted air it has yet to filter. This helps the purifier do a more efficient job. The air quality monitor lets you know what your room’s air quality is by showing you one of three colors: Blue means your air quality is good; Amber means it’s… well… mediocre; Red means bad. Pretty easy stuff, and easy to see from across the room. The various functions and features are backlit, so even in a dark room you won’t have any trouble selecting what you want. For those who are bothered by the indicator lights, there’s a night-time mode which turns them off. The unit itself is well thought-out and constructed. It doesn’t draw attention to itself, and will blend with most any decor. There’s no remote control that you’ll never use, and the controls are so well laid-out you’ll very likely never need to go digging around for the manual. My brother-in-law owns this unit, and it was on his recommendation that we ordered ours. We liked our first one so much, we quickly bought a second unit to go in our daughter’s bedroom. The difference has been striking. Now we only have to deal with wildfire smoke when we venture outside. The dry eyes and sniffles have reduced dramatically. If that sounds like the kind of world you wish to create for yourself in your own home, why not place your order today?

I did a ton of research and the best bang for your buck seems to be this model. It's still quite new at the time of writing this review. But stand OUT features here include: - Carbon and Hepa filter are individual, not bonded into one filter like so many of the budget purifiers have. This is REALLY important because the carbon filter might need replacing before the hepa, with this unit you absolutely can do that. Other purifiers require you to replace both since it's bonded together. - the Ionizer is optional, it can be turned off for those who do not want this, some brands do not allow this It does work. Verified with my air monitor , the minute i turn this on the PM2.5 drops in my room. However my VOC numbers only had a minor drop. It's so close, ALMOST perfect. Great price... but here are the issues you need to watch for... - LOUD. it has 4 fan modes + sleep mode (so 5 modes). Fan modes 2-4 are a joke, it's so loud I can't imagine anyone wanting them. The LOWEST fan mode is kind of loud still. I just can't use it, I don't think others will be okay with this getting work done or by their beds. HOWEVER... The sleep mode is great, and I think most people will be pleased by this noise level. However you can hear it if you listen for it, so for very sensitive people it might still bother them. I'll pretty much use sleep mode always, I have it by my desk and it's the only suitable mode. - it doesn't remember your settings! This is the most annoying part. I'll have the ionizer off, sleep mode on, and that's basically my settings, I'll never change them.... but when you power off the unit, leave the plug in the wall... it still forgets. I set up the app and it has the ability to turn the unit on and off remotely. Meaning the unit doesn't fully power down right... but it STILL WON'T REMEMBER your settings! Even the app won't remember and reapply them. The app by the way looks like its from 10 years ago. If I click the button to order replacement filters it doesn't actually send me to the filters I want, just drops me off at a generic link where I need to find the right filter I need. It's like this company doesn't want to make money lol. Otherwise it's not hard to use. It's a big boy unit. I wish it was smaller for my use case, which is a desk area in my bedroom. But unfortunately you don't get get the 2 pluses I mentioned above with smaller units. Fortunately my 2 gripes can be patched in a update... they can update the app to at least remember your last settings... tune the fan speeds across the board. But I don't have high hopes judging by the quality of their app software so far.

Field Guide to Domestic Happiness Species: Homo sapiens domesticus Habitat: Suburban living room Observed Behavior: The Atmospheric Incident In quiet homes across the world, a curious biological phenomenon occurs. A member of the household, believing themselves alone and unnoticed, releases what scientists politely call a modest but fragrant atmospheric disturbance, also known as a methane bloom. It is often accompanied by two defining characteristics: • a small but decisive sound • a rapid expansion of odor into the surrounding ecosystem The human assumes the event will quietly dissipate into the environment, carried away by the gentle currents of indoor air. But the modern home contains a vigilant predator of airborne impurities. The Winix 5510 Air Purifier. Compact and deceptively elegant, the Winix occupies its territory with quiet authority. Beneath its smooth exterior lies a layered defense system: a true HEPA filter to capture microscopic particles, an activated carbon layer to absorb odors, and the curious phenomenon known as PlasmaWave technology, which gently breaks down pollutants drifting through the air. Ever alert, its internal sensors constantly survey the atmosphere of the habitat, measuring subtle changes invisible to the human eye. Within seconds of detecting an atmospheric disturbance, the machine awakens. Fans surge to life. Air rushes through the filters with the urgency of a wildfire response team. A red light ignites like an emergency beacon. The human sits silently, staring at the glowing red bar, realizing two uncomfortable truths: 1. The event was not as discreet as originally believed. 2. The machine has no sense of discretion whatsoever. For several minutes, the Winix continues its noble work, cycling the air and restoring balance to the domestic ecosystem. Eventually the red light fades. The fan slows. The human exhales in relief, convinced the crisis has passed. Harmony has returned to the environment. Across the room, the Winix sits once again in stillness… patiently monitoring the air, waiting for the next disturbance in the ecosystem. The human, having learned nothing, continues to blame the cat. Nature, after all, is a cycle. Final score: Human 0. Winix ⭐⭐⭐⭐⭐

I've been looking for a whole room air filter for a while, and Winix was the brand that I'd focused on due to the features, price, and filter replacement cost. That said, I finally committed to purchasing this model, and so far it has met or exceeded my expectations. For reference, this is for my 17x20 master bedroom (340 sq feet) and the unit is specced for 360sq feet. I have berber carpet in my bedroom and it's always given off a 'carpety smell', which I think is the backing oxidizing and crumbling with age. It's very noticeable to me but has never been obnoxious, just an annoyance, but finally wanted to do something about it. First off, this unit is about the size of a common room dehumidifier, so it's not small, and not huge. It doesn't weigh much either. The modes work fine, but I'm not sure exactly how it uses the sensor on it to detect air quality. Mine mostly stays blue, but flips to amber and red occasionally. There's very little distinction between the amber and red color also as it's either "Yup, that's red.", or "That sort of looks red." All the air quality mode does is change the fan speed to a faster setting. Within a day or two of using this on the auto setting, the above mentioned 'carpety smell' is all but gone. I keep it on all the time on auto mode, and it mostly has the blue air quality light on all the time, and runs on the low fan setting. At that setting the sounds is barely audible. I'm hypersensitive to smell, sound, and light, so that was very important it checked all the boxes for me to be something I could keep. It definitely does it's job filter the air/smells, the noise is barely noticeable (it does get louder on the higher setting, but that's clearly to be expected), and the lights on the unit are not that distracting. What sealed the deal for me in keeping this unit was the night mode. When it detects low light levels, it flips the unit to a slower fan speed than the lowest setting speed, and turns off all the lights on the unit except the small white 'Sleep/zzz' one. As mentioned, I'm hypersensitive to a lot of things and need total blackout in my room to sleep, and this light is barely noticeable, and the sound can barely be heard on the 'sleep' fan speed. I have this at the foot of my bed, faced away from my bed, so I don't have direct line of sight to the front of the unit. The 'official' Winix replacement filters cost about $50, which to me is a bit high. There are different types of aftermarket replacements, and I cannot attest to those here, but there are a few that appear to be exactly the same as the OEM one. The filter set has a large paper element filter, and a black carbon one that looks like a 1/2" thick plastic rectangle with tons of little honeycomb chambers and granulated activated charcoal pellets. That's what removes the smells and they definitely work. I will be trying aftermarket filters in my unit after using the provided OEM ones once I know how long they work, how well they work, and how long they last. Overall though, this is the best room air filter unit I've seen and I would recommend it. ***Update*** 01/30/24 As an addendum to my original review, the air filter that came with this unit lasted about a year of continuous use before the 'check filter' light came on. When I took the old filter out, it definitely had worked because I could feel and see fine white dust on the main filter, like what you'd see if you cleaned a vacuum air filter. Also not sure how the "Smart Sensor" in this thing works, but it WORKS. If you spray an air freshener in a room away, it picks it up and ramps up the fan. Walk by it after gargling with mouth wash, fan ramps up. Make a toot near it, it definitely ramps up. Nice to have a product that works how it should!

The auto setting of this air purifier is good: it detects when the air is dirtier, indicates that with an orange or red light, and increases the fan speed accordingly. This happens when I run the filter in my kitchen and it reacts to the smoke from the stove or oven, even when it is not enough to see with your eyes. Sometimes the light changes to orange or red in the bedroom right after someone coughs or sneezes, so I think that indicates that it is probably cleaning the air of infectious particles breathed out by someone who is ill. Sometimes it indicates dirtier air and it is not obvious to me what it detected, but I trust it since it does detect things I know about like cooking smoke and sneezes. Most of the time it runs on the lowest and quietest setting (which is reasonably quiet), but runs higher when needed. It also detects the light in the room, so if it is dark at night, it runs an even quieter mode. My sister had bought one of these air purifiers for our elderly parents in California. I don't remember whether it was smoke from wildfires or Covid that first motivated my sister to buy the air purifier, but it has been good for both of those health hazards. So when I visited them, I had seen how the auto-detection worked and when I had vacuumed out the filter for them, so I could see that cleaning and changing the filters was easy. I first bought a unit for myself in 2023 when smoke from wildfires in Canada blew down and made the air in Chicago hazy and orangish and beaches were closed because the air quality index was over 100 and was bad enough that people were told to stay inside. Our HVAC system has 4" MERV 13 filters, but I felt that smoke was still getting in whenever we opened our doors and the HVAC filters were probably not filtering enough to completely clean the air. I also have pretty bad seasonable allergies, so this unit is good for cleaning the pollen out of the air in my house. Just a couple months after I bought the unit for my own house, I sent another unit to my adult child in DC when the smoke from Canada blew into DC. They liked it so much that this year they bought one for their workplace office after they had to start working part-time in-the-office rather than fully remotely as they had done when they were hired during the height of the pandemic. The unit is a bit heavy at 17 lbs. So I got tired of taking it up and down the stairs from my bedroom to the dining room or kitchen and I bought this second unit for our household. It has a different style of activated charcoal filter that has gravel-sized pieces of charcoal in a plastic cage instead of the black fiber filter that the previous units used. The new charcoal filter is supposed to last longer than the fiber filter so I think it is better. I found that generic filer replacements of the HEPA filter and the charcoal filters fit my first unit just fine. I haven't looked for replacements for the newer type of charcoal filter yet.

** 3-week update ** After a few weeks a clicking noise developed in the fan when running on the sleep (lowest) speed. Looking at the fan it appears there maybe an imbalance that over the weeks developed into a motor shaft tapping. Make sure to inspect your unit for a balanced fan. I just issued a replacement on the 5500-2 so we'll see what happens. ** Original ** I spent weeks comparing units on Amazon and elsewhere. I didn't want to spent > 200 on an overbuilt fan, or be stuck buying overpriced filters. I ended up buying the Winix 5500-2 and Renpho AP002 and first impressions with the two units are that they both appear well built, quiet, and have the automatic mode I really wanted. TL;DR; Winix 5300-2 - Quieter w/Smarter hands off Automatic technology & Ionizer - Set and Forget! Winix 5500-2 - Identical in Black w/Remote & washable carbon filter Renpho AP001 - Incredible unit, Amazing filters, Low cost ownership! Renpho AP002 - Almost identical, slightly more air volume FILTERS The Renpho filter has a price and feature advantage over the Winix. Both units have H13 Hepa filters, both have the honeycomb active carbon filters (for capturing VOC), and both have a washable pre-filters for catching large particles. The Renpho however has 2 bonus layers, a microbial coating on the Hepa filter, and an additional charcoal filter sitting before the carbon filter to collect larger particles. The Winix does claim the active carbon filter is washable - Renpho does not make this claim, however both appear similar so it maybe purely marketing. The Renpho filter is shorter and fatter - if you ran the numbers they both likely have similar surface area, thought the Winix is CADR rated for 360 sqr/ft while the Renpho is 330 sqr/ft. They are close. Renpho OEM filters sell for $25 for a full replacement. Winix OEM filters sell for $50 for a full replacement. Renpo claims the filter should be changed every 6 months, Winix claims every 12. I assume this is reflected in their price strategy, however since the filters are so similar, I doubt both claims can be true - and this all depends on how dirty your air is! So cost of ownership is likely less with the Renpho. AIR IONIZATION The Winix comes with an Ionizer (called Plasmawave) and Renpho does NOT. The Ionizer charges any particles passing through the unit so they are heavier and will float to the ground and out of air. If you're concerned about Ozone gasses, then this is a feature you can disable and is not a feature on the Renpho. SOUND This is a real issue for me - I am sensitive to sound and like the home quiet at night. Deciding on a unit for my children makes this even more important, and I don't want to force them into a white machine for air filtration. In Sleep mode the Winix is significantly more quiet at (advertised) 26dB where the Renpho is at 35dB. With the Winix 10ft from the bed I can just barely hear it. The Renpho is noticable but not "loud". The Winix appears to have 5 speed modes, Sleep, Low, Med, High, and Turbo. The Renpho has just 3 modes, Low, Med, High, with Sleep mode being the Low mode with lights off. Here's the rub however - outside of Sleep mode, the Winix sounds "louder" having a higher pitched whine while the Renpho is more of a hum. If I was going to just set this on High in a corner and forget it, then Renpho is the winner. For a quiet bedroom the Winix appears the winner. AUTOMATIC MODE This was a huge feature for me and the Winix is a much "smarter" unit. Both units have a similar Automatic feature, sensing the air, bringing the fan speed up or down according to the readings. Both have light(s) indicating the current air quality reading. The Winix however had a light sensor that, when the unit is in Automatic mode, will place the unit in Sleep mode when the lights go out (for more than 1 min). In the morning the unit goes back into Automatic mode. This is huge if you appreciate how quiet the unit is. You can set the Winix to Automatic mode and not touch it until your next filter cleaning. If you wish to use the Sleep mode on the Renpho you will need to push the Speed button to cycle through the speed options back to Sleep - and then again in the morning cycle back to Auto. In reality you maybe better covering the lights with black tape and leaving it in Auto or just leave it in Sleep mode permanently. REMOTE Winix has one, Renpho not - for my needs this is a non-issue. CHILD LOCK Renpho has one, Winix does not - this is a great feature if young kids are around! APPEARANCE Personally I think the Winix looks clean, modern, and the black color blends well into a corner near furniture. The Renpho AP002 like the Renpho AP001 have their signature funky look which is fine but not as refined. It's an air purifier, so who cares, but it is also a visible piece of equipment in your home. For us the Winix seems more appropriate for a bedroom, the Renpho for a living room. Winix higher cost of ownership justified by the features and sound levels, Renpho for lower ownership cost. If the Renpho unit was QUIETER (ahem - hint hint Renpho) then I would just go that route - save on upfront and ownership cost. SIMILAR MODELS The Winix 5300-2 and Winix 5500-2 are the exact same physical unit in different colors with different filters. The 5300 is gray, the 5500 is black. Only the 5500 has a remote. The 5500 has their "advanced" AOC Washable Active Carbon filter, while the 5300 has a disposable active carbon. The 5300 Hepa filter is slightly thicker (good) and you get 4 disposable filters with each replacement. If you buy the 5500 and don't like the washable filter it comes with you can buy the 5300 replacement pack and use them instead. For $23 more we went with the Winix 5500-2 to test the AOC filter, and for the black aesthetic. Currently you can get the 5300-2 for $129 (Amazon) and when I purchased the Winix 5500-2 for $152 (now listed at $159 on Amazon). The Renpho AP001 (often found as RP-AP001 or AP-001) and Renpho AP002 are very similar products, both using the exact same filters, having different aesthetic designs, and with the AP002 having more airflow (for supposedly the same sound levels) and covering 30 sqr/ft more space. The AP001 has a dedicated Sleep button while the AP002 Sleep mode is the first option on the Speed cycle button - more daily button work for you. Currently the AP001 sells for $99 (Renpho direct) while the AP002 for $137 (Amazon). I bought the AP002 thinking the newer model maybe more quiet than advertised. If we get another Renpho it will be the AP001 for $37 bucks less.
