HPA300 HEPA Air Purifier, Airborne Allergen Reducer for Large Rooms (465 sq ft), White - Wildlfire/Smoke, Pollen, Pet Dander, and Dust Air Purifier

Sending your firstborn off to college in the midst of a global pandemic is kinda scary. To soothe your own nerves you think "Hmm if I buy him an air purifier for his dorm room maybe, just maybe it will capture some of those rogue air particles which might cause him discomfort (allergies) or harm (illness)." Of course the teen gives you the eyeroll when hearing about the idea. Parents of teens, *you know that look. "I don't need an air purifier!" insists he. I buy it anyway. I tell him it will make a great white noise machine. He rolls his eyes at me again. But, it makes it into the fully stuffed car as we get ready to roll on down the highway to get to the campus of higher learning. Pretty sure he was just humoring me as he packed it but hey, whatever it takes. I take no chances. *I* set it up in his teeny tiny dorm room (with which he will share with a roommate). Figured that while he might unplug it and shove it under the bed as soon as I leave, I at least gave it a shot. A few weeks go by before I happen to bring up the topic of "Hey, by the way, how's that air purifier working for you?" He says, "You were right (I try not to fall over hearing those rarely before uttered words). It makes a great white noise machine. We barely notice it on anymore." :::Victory dance on my end of the phone::: Before he's getting ready to come home for Thanksgiving, he happens to mention "Hey there's a red 'check filter' light that lit up on the machine. What am I supposed to do with this? It still seems to be working completely fine." Since he's going to be home for 7+ weeks (more pandemic disruption) before Spring semester starts up again, I just tell him to bring the whole machine home and we'll deal with it over break. Home comes the lad with his machine. We casually open it up to check the filter and "OMG!!!" Uh yes. This machine works and apparently works very well!! Mind you, I personally had installed the brand new and spiffy clean filter prior to sending it off to school. The dorm room was very tiny and was in fact pretty clean when we arrived. The boys chose not to use a rug in the room so it's not like there was "carpet fluff" to errantly fly around the room. They're both the studious, pretty overall clean guys who really couldn't do much to create dirt in the room as there were all kinds of pandemic guidelines/restrictions in place. But THIS (see photo) is what the machine captured between the late August & mid November! Pretty disgusting to see but also pretty darn awesome to see how well the machine worked. And the college lad? No more eye rolling when it comes to the mention of an air purifier. He is now completely sold on it. He recently came home for the summer & while most everything else from his dorm room got tossed into a corner of the basement not to resurface again until the trek back down to campus in August, I noticed that the air purifier (with a nice fresh & clean filter) is carefully set up in his bedroom & running 24/7. Catching any wayward dust particles....and serving as a good white noise machine. Buy this machine. It works. Pictures don't lie. I shared this pix on a college parents' message board. LOL Too bad I couldn't get commission on the ensuing sales because I can tell you, that a whole bunch of parents rushed to order one of these for their kids' dorm rooms after seeing the picture I took. I myself ordered another one (different size...larger) to place in our basement living area. And will be looking to order another one for our bedroom. The teen's not the only one sold on this machine. I am too!

I've had allergies all my life. Over the years I have purchased other brands and found them ineffective. The technician who services my heat pump didn't recommend any air cleaner/purifier. I read the reviews for this unit, HPA 300, and decided to try it anyway. So glad I did. It does a great job circulating air in the room, and pulling dust out of the air. My house is dusty and I don't like housecleaning. I have noticed a big difference in how much less dust accumulates on the furniture since I have been using this unit. Even my cat, who has chronic upper respiratory issues, sneezes less. Once a month I vacuum the prefilter carefully, even thought the instructions said not to. That saves the cost of replacing the pre-filter every month, and I have not noticed any loss of effectiveness. The carbon pre-filter is primarily for odor removal, and that is not an issue for me. The carbon's ability to remove odors will be exhausted after 3 months or so, but it will still remove just as much dust. I have not had to replace the HEPA filter yet, and I also vacuum it carefully. Noise level on the low setting is acceptable. Louder noise on high took some getting used to, but it doesn't need to sat on high for very long. I like the performance of this unit so much, I am planning to add another unit soon. The HP300 is the largest unit, but handles a greater volume of air filtration. Definitely recommend the Honeywell HPA 300.

Over the past 7 to 10 years, we have been purchasing this exact model for our house, and all of them still work perfectly. We live in a house that was built in the late 60s, have two cats and two dogs, and three teenagers. I am HIGHLY allergic to cats - if I pet them, I have to wash my hands immediately. The amount of pet dander in my home is outrageous. We also recently had our subfloor replaces in several areas of the house and it has caused a massive amount of wood-colored dust (we need to have our duct work redone and suspect it is a part of the dust issue in the house). These are strategically placed around the house for maximum cleaning. One, these are the best because you can place them against a wall. The downside is that it will create more dust on the wall near the air purifier. Simple logic - the air exits the top and what hasn't been sucked in through the device travels on a path that hits the wall. So you have to dust your wall - no big deal. I have to do that, due to just being noticeable, about twice a year. The hepa filters only need to be changed once a year, and the pre-filter every 3 months. When I change the pre-filter, I normally run a vacuum around the edges where there is dust buildup. This is unavoidable for any air purifier (I have tried many versions and keep coming back to this one). WHAT MAKES THIS THE BEST: - Durability. I have had our first one we ever purchased (maybe 7 to 10 years ago) running all day at the highest speed without going on turbo, consistently and there has been zereo degradation to the unit. It works as well today as it did when we purchased it many years ago. - White Noise. I like white noise, and unless it is on turbo, you don't really think about the sound once you get used to it. My pets are not afraid of it, which means it's just white noise to them as well. - Frequency of filter changes and types of filters. Sure you can buy the name brand filter replacements, but the generic ones are just as good and you save money. Honeywell's products are excellent from my experience, and the device itself has stood the test of time. For the filter replacements, you're just paying for the Honeywell name if you choose their higher priced replacements. -CLEANER AIR! Like I said, we have four of these now. One in my son's room which is a mother-in-law suite - the size is sufficient for the size of his room. The room was an addition built in the late 80s, early 90s, and the door to the outside isn't perfect (old house issues), and some outdoor allergens get into his room. Having one in his room has greatly reduced allergies during high pollen season (we are in the south, pollen is around all year). Since adding the most recent unit, the amount of the brown dust I have seen has been reduced. We also have one in our living room that is large enough to seat 10 people, and a home office. My newest one is located in another home office that I share with my dogs and their crates. Again, allergen reduction was easily noticeable once it was in place. The last one we own in in our bedroom because of my allergies (no pets allowed). I know it has made a difference because I have significantly less allergies in the morning than I did prior to putting one in our bedroom. My entire life has been one allergy attack after another, even after taking allergy shots. These units help me live life - WITH PETS I AM ALLERGIC TO - without a constant runny nose and itchy eyes. If you are looking for a unit that will not die in a year, or start making strange sounds after a few weeks of use, THIS IS THE UNIT YOU HAVE BEEN DREAMING OF! Like I said, we have had the same one for many years (we got our first one at a big box store and I can only guess that it was at least 7 years ago, but I suspect it was closer to 10).

AMENDED NOTE: While I'm happy with the purifier, part of the reason I selected it was because the replacement filters were much more reasonable than other brands. Since I purchased the unit last October, the price for filters has TRIPLED. This is b.s. on Honeywell's part. That's how they get you on all items that need replacement filters or cartridges. Very disappointed. I'm giving a conservative 4 stars for now, because I've only had the product a few days and will be curious as to its longevity. But already, this is far superior to the Idyllis brand purifier we purchased previously from Lowe's. Our house is 1920s, we have 3 dogs, and live in a busy city with fairly high humidity. All these factors can make it more challenging to keep your home smelling fresh. I unpacked the Honeywell purifier on Saturday evening and turned it on. By the next day, I saw an improvement, and by Monday, the difference was unmistakable. Granted, during this period, I did open windows for fresh air and wash some rugs, but I have to give most of the credit to the purifier. The previous smells just seem to be almost completely gone, and I have a pretty sensitive nose. It moves a lot of air, yet its noise is not overwhelming like the previous model we had. It's simple to operate and the replacement filters are 1/3 the price of the others we used to buy. Granted in the X-large model, it does take 3 filters when you switch out, but still, at about $11 each, it's less than I paid for one Idyllis filter. One feature I just love is the dimmer light: Press once and it dims the 'on light' areas, press again and it turns them off altogether. This is especially helpful if used in a bedroom, because some appliances glow so bright that it's distracting. I noticed some reviewers complained about a strong plastic smell when it ran. I don't know what happened in their case, but I have not had this experience. Now, I did notice a plastic smell when I first unwrapped the device - but that's likely just brand new plastic outgassing, after it's been sealed up in a bag. The odor was detectable but not overpowering, and by the next day, had dissipated. If you're especially sensitive to smells, you might try leaving the device outside in a cool, dry place for the first night and let it air out - similar to what you can do with memory foam mattresses. In general, I would really recommend the Honeywell HPA300 for anyone looking to freshen your indoor air. Not only has it worked quickly, but it's at least $60 cheaper than anything comparable I saw at the big box stores, while delivering more powerful performance.

The reviews were excellent on this filter system & made me choose this over the others. One in particular explained how they were able to clean the HEPA & charcoal filters so you wouldn't have to buy new ones as often. Had this for a couple of months now & I must say that it sure pulls a lot of dust out of the air. We have it in our living room. I'm not sneezing as much as I used to. We've taken the advice on blowing out the charcoal filter with our air hose, and banging the HEPA filters on the sidewalk to dislodge the dust. Works like a charm. Had to do that after hardly two weeks after setting up the machine when it didn't seem to be pulling out as much dust as before. It was quite full of dust. The filter light never came on. We now check it every 2 weeks...it's dusty every time...doing its job. It's quiet on low, but gets noisier when turned up. We keep it on low. Great product. UPDATE: We've been using this now since February & after about 4 months, the HEPA filter light finally came on. We banged the filters on the ground (like a previous buyer suggested) but it didn't make the light go out. We went online to find replacement filters & ordered a box with 2 sets in it, so we should be good on filters till the end of the year. We only operate this machine when our windows are closed, as I don't see any value in filtering outside air that comes into the house through our open windows. Every couple of weeks, we take the foam charcoal filter out & use the handheld vacuum attachment (with the brush) to vacuum the dust off. Once a month, I vacuum that filter, then rinse it off & air-dry it overnight (turning off the machine until the filter is dry enough to be put back in). This machine is quiet enough to be put in a bedroom (when on lowest setting) & makes excellent white noise for those who need it. I've never had a filter machine like this before, so I don't have anything to compare it with, but it's doing a great job of removing dust from the air in our livingroom, where we spend most of our time. I also like that you can turn down the brightness of the instrument panel on top, or even turn almost all of them off, to cut down on extra light & power.

After a few months of debating whether or not to get an air purifier, as well as which one, I finally decided on this one. I bought it for my "game room" which is approximately an 18' x 18' room. I have a pit/lab and border collie/lab and this room is connected to my back porch. It's also where their crates are, where I keep them gated in from the rest of the house when necessary since it's hardwood and tile (when it rains or in the winter months living in Upstate NY until they dry off), and also the room where I have been working from home since the woman took over my upstairs office while she works from home and we have an 18 month old. The border collie attracts a ton of dirt and dust of course so not only am I constantly cleaning all the dirt and dust but also have been sneezing a lot and feel like it's impossible to remove the smell. The first air purifier I received on Wednesday, January 13th 2021. I opened it and immediately noticed the top had a piece broken off (picture attached). I know I probably could have glued it back together myself, but for how much the item cost and having an 18 month old running around potentially grabbing it, I didn't want to risk it and also obviously wanted it to be without issue. I requested a replacement online, put it right back in the box, and brought it to the UPS store within an hour of receiving it. They put the replacement order through and said it would be delivered yesterday, Monday January 18th 2021, which it was. Again I opened it right away. This time there was an additional box around the item's normal packaging. The item came in with no exterior issues. I removed all of the plastic from the filters as well as on the outside of the air purifier and plugged it in. I could tell the air quality within 6-8 feet or so of the air purifier was better pretty quickly. I'd say within an hour or 2. After over 10 hours of running it does seem better from an estimated 12 feet or more away. I can't say for sure it's fully cleared up the entire room yet, but I can say it's much better. Turbo clean is pretty loud, but I only had it on for maybe the first 20 minutes of turning it on to get things moving. I don't mind the noise either as I'm used to having a fan on. General clean it pretty quiet to me and is the only other setting I've had it on. Germ cleaning is quieter and Allergen is a bit more noisy - just from switching through to check. The 2nd picture attached I just took of it. It's not in it's permanent location, but for overall context purposes I figured it may help me gauge how well it works. You can see the dust on the subwoofer behind it, the dust on the tv stand to the right, some fur on the ground, and to the very left is the border collie/lab's crate. I dusted, swept, and mopped about a week ago and give the floor a quick sweep 2 days ago. So my goal is to do the same thing and see if the air purifier prevents the dust from accumulating so quickly. I haven't used the timer, but I don't really see me "needing" it very often so I'm going to assume it works as intended. It's light and easy to pick up with the handles on the sides on top and the noise is fine, so I'm giving it a 5 star. If it doesn't prevent the dust issue I may come back and change it, but so far I'm happy with it. Although I had to return the first one, I understand things happen and the replacement process was pretty simple so I don't think that's worth taking a star away.

This is going to shock you, but somebody lied — well, exaggerated — about the capabilities of this machine. The marketing folks say it will clean the air in a 1500 square foot space. And it probably would if you gave it a long, long time to do it. More reasonably, it will clean the air in one room. It will cycle the air in a 310 square foot space five times an hour. I figured that all out before I bought it. I’m using it in my bedroom. I’m going to buy another one for the living room. The good news is that it does a great job and it does it quickly. I,ve been sniffling around for a week or two now. I cranked this thing up an hour or two ago and soon noticed my sniffles have disappeared. As far as I’m concerned, that’s a big win. I strongly recommend you buy however many of these you need. You’ll be glad you did.

Our house does not have an air exchanger so suffers from stale air and pet orders. Been wanting one of these for years but the price was always high. I see now they are about 1/3 the price they used to be so tried it. The space I put it in is just over 300' so I know I'm pushing it. Plugged it in, put it on low and in 2 hours it was a different room. My partner, not knowing I bought this, came home from work that night and asked me what I did because the air felt so much better. It made that much a difference that fast. Regarding noise, on low it's a little quieter than the air from the HVAC vents and easy to ignore. Higher than low It's too loud for me. Even on low it's just a hair too loud for me to want to sleep to as well so I turn it off at night. At a low setting it is a hair localized for my room getting one side but not the other. I've been moving it from side to side of the room about once a week and that keeps it balanced. I often turn it up if I am leaving the house for a few hours to help purge the air. Besides stale air we have a cat and the space often smells "catty" or I can smell the litter box from the next room. This took about 2 days to completely remove those smells. If I move it to the bathroom with the litter box it takes a few hours to completely remove all litter box and bathroom odor. I also have noticed way less dusting I have to do now. The pre-filter has gotten full of cat hair and dust quickly so I have had to blow it out with an air compressor to not have to keep replacing the filters but it's not that bad. In hindsight I see the newer models take 3 layers of filters so you can put a specialty filter for kitchen, smoke, pet etc. This unit uses 2 layers not three but still works well, I would have gotten two 200' tower units with this instead of this one larger 2 layer. The 3 layer newer ones are about 2x the price however. We did get a 3 filter for a smaller room. I like the smaller size but it honestly doesn't seem to work as well as this one, probably as it has less air flow being a tower with no large flat side. The timer function is mostly worthless. I don't need it to turn off after a certain number of hours. I need it to turn off at night, and turn on in the morning with a clock function like my thermostat. The upgraded unit with the auto feature is also worthless. It doesn't sense the room properly and says its fine when my nose says its not. Overall this thing is amazing and makes the living space feel so much better and actually works better than the upgraded unit. Very much worth the price. Only caution is maybe get a slightly larger unit than you think so on the low setting it covers your room space.
