Alen - BreatheSmart 75i

We use an Alen 75i downstairs in main living space area and two 45i's upstairs, one in the nursery with odor filter that is surprisingly effective and the other in the master bedroom. Not cheap upfront and filters are pricey, but they've worked well for us for about two years now and it's nice to be able to schedule them in app so they don't run at the same time as humidifiers in the winter etc.

Alen is the best of that group by far. And especially since this is r/BIFL - they offer a lifetime warranty as long as you buy your filters from them (or authorized 3rd party) Remember, get a unit bigger than you think you’ll need so you don’t need to run it on full blast constantly and be overwhelmed by noise - another plus for Alen is that they are insanely quiet. I have a 45i and 75i and they are excellent. The VOC filter has a crazy amount of carbon in it too to help with smoke. I believe they are also one of the few manufacturers that publish their carbon numbers in their filters. A lot of others don’t.

Alen is another brand to look at. Very quiet. Their 75i would be a good fit to not have to run it on high all the time. Plus you get a lifetime warranty if you buy filters from them or authorized 3rd parties.

Alen 75i with the VOC filter. Lots of carbon in there to help with the odors you mentioned. Yes there are others with even more carbon but the price starts to go through the roof.

Not a Dyson. Seriously. Alen, Coway or winix.

Dyson in general is not known for high quality especially for the price they charge. Also their customer service is shit. The other 3 I listed are much better options. You’ll want as much carbon in the filter as possible. Alen VOC for example.

I don’t work there, but +1 for the Alen 75i. Excellent unit, super quiet and their odor and VOC filters have a bunch of carbon. The filters last 12-15 months, so don’t be sticker shocked at the price of the filters. They tend to last longer. So running costs are actually less than competitors. Also, buying filters from Alen gets you a lifetime warranty.

If you want BIFL the only answer is Alen. They offer a lifetime warranty as long as you buy filters from them or from an authorized 3rd party. The 75i and 45i are excellent depending on your space. I’d get the VOC filter as well.

1) Ask r/airpurifiers 2) Alen is really the only true BIFL brand because they offer a lifetime warranty for as long as you buy genuine Alen filters. Plus the filters last a long time too and they are incredibly quiet. Coway and Winix are good too just not at the level Alen is. **Avoid Dyson, blueair and Levoit. They’re junk.** 3) As for sizing, this part is important: most manufacturers advertise crazy sqft numbers (1,000sqft+ for a tiny tabletop unit) just know that most of the time this is disclaimed by stating it can filter all the air in a 1ksqft room ONE TIME per hour. If you actually want to filter your air, industry standard is FOUR times per hour. So in reality, that 1ksqft unit is really only good for a 250sqft room **on full blast** which is usually loud. What kind of space are you trying to purify? An Alen 45i or 75i is great for living rooms and open spaces, then A flex or 25i bedrooms would work well.

If you want to buy off the shelf: Alen 75i (or two) with their VOC filter. Should be right on budget. Although I do believe they have commercial units as well. Check their website for commercial pricing.

Alen is excellent and built like a tank. Also literally BIFL as you get a lifetime warranty as long as you buy filters from them or an authorized 3rd party. Depending on your room size, 45i or 75i are great. (Remember the advertised sqft you see is often 1 air change per hour, if you want it to actually work well, 4 or 4.8 (industry standard) ACH should be used.

I have 6 Alens. 2 x BreatheSmart 75i, 2 x BreatheSmart, a T500, and a Paralda. I like them. They are quiet, the sensors (on the 4 bigger ones) seem to be accurate and ramp up cfm when air quality calls for it. I live in the lightning capital of the world... God's Lightning Rod, FL. I had 2 older ones that got hit and the LEDs went out. It still worked fine, it was just the little LED bulbs that didnt work. They sent me 2 new units with no hassle. The filters are not cheap, but I am happy with how long they last and how they perform. I'd 1000% buy from them again.

Alen 75i for sure

I eventually went with the Alen BreatheSmart 75i for my home, and it's been solid.

Alen purifiers. I have 3. They’re amazing, perfect background noise (I’m sensitive to sound), and work really well to the point anyone who stays at my place doesn’t deal with allergies. I own 1 cat for reference and it helps with pet hair thanks to the ionizer option. I have one i75 and two i45s.

I've had an Alen 75i ( https://a.co/d/fztp1rY) in our bedroom for 3 years now. Nice unit and is quiet.

If you're looking for the best value for a space that large you should look at the Lifubide Y1000. For what it is it's hard to beat. AirDoctor is fine but their units are a bit noisy and their filters are expensive. iQAir is great but it's noisy on its highest level. Wanted to like MedifyAir but had a horrible customer service experience with them and not only that but they would not confirm that their filters were actually HEPA nor would they tell me the amount of carbon in their filter they said that was a company secret.. so that to me means they lied.. just not a fun company to deal with at all. The Dyson are basically just big fans, they do help with formaldehyde but that's about it, they are way overpriced for what they are and boy their customer service is on a whole new level of hell.. I won't ever recommend a Dyson to anyone ever again. Blue air I'm not a fan of and their always on ionizer isn't wonderful. My favorite air purifiers are Alen Breathesmart 75i, super quiet, moves a ton of air and is also super expensive. I also really like Oransi Mod+ but their air purifier prices have doubled recently so it's hard for me to recommend them anymore, for what they charge there are better alternatives.

I have a 75i in my house with an open first floor about 1150sqft and I have even better extraction than it sounds like you do. I like that it gives me a visual indication of AQ with the light but it goes pink (the worst AQ light) whenever we sear things with the extraction on. The fan will run on the highest setting for 20 minutes after searing/sauteeing then step down through the rest of the speeds. I know people will say that they’re overpriced but they’ve worked well for us in our home. We have 4 and price hasnt been my primary decision driver. Noise, filter quality, an longevity have been. We also have focused on modifying our air handlers for HEPA filtration without altering static pressure. If you have the space near the returns to do so it is a big bang for your buck.

The one with the charcoal element keeps things smelling better which I prefer in the kitchen. It’s not the absolute highest filtration they offer but I think it’s still within spitting distance of the others.

I have Alen air purifiers… a 75i and two 45i. I notice sleep better when I run one at night & I vacuum the filters weekly since I have dogs. My neighbor’s new born always has a runny nose- they have three dogs & a smaller place. The Mom loves cleaning- place always looks great, vacuums pretty much daily. I loaned the 75i to her for a month… the filter came back completely matted with dog hair- and her baby had been sleeping a lot better…

I feel like I have the flu every time I visit Utah, groggy in the morning & headaches, poor sleep, etc. Brought my air purifier with me from home & I feel cured! I have an Alen 75i. Sounds like there are more inexpensive options that work great. I lent it to my Utah neighbor because her new born was congested all the time & had trouble sleeping. The air purifier made a huge difference! It Is Very Worth It!
