## Questions & Answers

**Q: Does this air purifier have an air intake on the front and outlet on the top ? I live in a small place and would like to tuck it against a wall.**
A: Hello! Air intake occurs on the side, air outlet is located at the top so placement with the backside along a wall is totally fine. We hope this helps! Sincerely, Alen Customer Relations Team.

**Q: Mine has a wifi indicator above the lock button. what is that for?**
A: For those of you trying to setup the WiFi through Gosund, hold the auto button to put your purifier into pairing mode. One press will turn it on and the WiFi icon will flash, another press will turn the WiFi icon off; you will notice it flashes and eventually turns off if you’ve turned the WiFi off. Hope this helps.

**Q: how is this different than the Flex?**
A: Appears that the 45i has an ionizer, the flex does not

**Q: I have a wi-fi light flashing on the unit i just bought.  do these have wi-fi installed an is this active for ifttt?**
A: Hello, thank you for writing in. The unit does have wifi capability. It is possible to use TUYA's "Smart Life" APP, available on APP stores, to control these units. Download the APP and follow instructions to sync the unit. The unit can be put into pairing mode by pressing the Auto button for 5 seconds (the WiFi light will blink). At the same time, unit function with the Smart Life APP is not fully fleshed out or tested, and may be buggy. Alen is not presently set up to support the APP. I hope this helps - Alen Customer Team

### ⭐⭐⭐⭐⭐ Worth every cent, allergy relief almost immediately
*by J***G on January 31, 2021*

We recently got a mini schnauzer puppy a couple of months ago. I am highly allergic to most dogs and all cats. Even though the schnauzer is considered hypoallergenic, I know that no dog is truly hypoallergenic. We have a small 880 foot condo and keep her crate in the living room. Starting on the first evening we had her, my allergies started to flare up, as well as my wife's. This was not acceptable. I originally had a levoit large room purifier but knew it was time to step it up. After perusing Amazon reviews, I decided on the Alen Breathe smart i45. A major plus to this unit was the air sensor which automatically adjusts speed and intensity based upon air quality. When I first got it, I immediately plugged it in and it got to work. The air quality light showed red and it continued running at high intensity for several hours and I saw the air quality improving. After a day or two, my allergy symptoms were completely gone. I was ecstatic! This purifier is meant to run 24/7, so that is what I do. It is a LIFESAVER! Now we can co exist with our four legged friend in peace. Make sure to register on their site for the lifetime warranty activation. I also signed up for the filter subscription as it makes things easier than having to manually order. I would recommend this purifier to anyone who has allergies and/or wants better air quality! Can't give this thing enough praise. Note: Few comments here recommend the gosund app for wifi monitoring. While I tried doing so and it did work, I quickly cancelled the connection and deleted the gosund app. I think it's a security risk to give some unknown app your WiFi network password, and also when I contacted Alen, they said there is no app right now for monitoring purposes. The wifi capability is for remote troubleshooting if issues arise. So I recommend not using any third party app with the purifier.

### ⭐⭐⭐⭐⭐ Would recommend
*by J***Y on September 17, 2025*

This has kept out 1000 sq ft first floor nice and clean. It has been running nonstop for months without issue and has definitely reduced dust, smoke smell in the winter, and other odd smells when cooking. The charcoal filter helps the smells and the filter lasts a while

### ⭐⭐⭐⭐⭐ More sleeping, less sneezing
*by J***A on July 21, 2022*

It was summer in Seattle and the blooming things were exploding with delight, unleashing a blanket of pollen on the city and providing job security for the makers of Sudafed. I'd grown weary of sneezing myself to sleep at night and of constantly vacuuming up dust. It was the summer I turned to air purification for my salvation.I bought the Alen 45i on the recommendation of Consumer Reports. After a few initial hours on turbo, it settled into a quiet cycle on auto mode and I haven't had to touch it since. Pretty quickly, my dust level was significantly diminished and I was sleeping better. I found that when I walked downstairs in the morning I would immediately start sneezing, so I ended up purchasing the larger 75i for my living room (probably overkill for my space; it's a gigantic beast). Both units are extremely quiet unless they're on turbo — but they call it turbo for a reason — and they're super-easy to setup and use. They also look nice, and I like that you can turn off the display light on the 45i so it doesn't cast unnecessary light in the bedroom at night.So far so good on the filter, though I haven't had it long enough to say whether it's as long-lasting as claimed. Assuming it continues to perform I think it's worth the investment for cleaner air and better sleep.
