Alen - BreatheSmart 45i HEPA

We just bought 3 45i using the bundle deal. One with each filter “Pure, Fresh, and Odor”. We really like them.

We got Odor for the basement with the cat box, Fresh for the one in the kitchen and the regular Pure for the bedroom. I will say they all did come in the “pure” box, but they had the correct filters inside

Not smart but I have two Alens and absolutely love them. I've had an older Breathsmart for 6-7 years and still works great. Recently bought a smaller one for my gym/mancave and it's also great. Won't look for another brand if I needed another one.

I have two 45i Alen purifiers (First had an issue that doesn’t really affect usability other than it’s always on high speed and they replaced it for free, without asking for the original back. So I bought another front cover and now have two!) Love them. Filters are replaced about yearly for me.

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.

Have you considered 2 medium sized units placed strategically? For a space that size it may be more effective. 2 Alen 45i’s + the VOC filter may be worth considering as well. And I believe they are buy 1 get on 50% off right now.

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.

We have an Alen HEPA that we’ve owned for over 7 years. A couple of filter changes but still running like new.

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 use Alen air purifiers in my apartment. It’s made a huge difference. I’ve wanted to become a “windows shut” apartment for a while, but whenever I would try it, I always found the apartment getting too stuffy. Now though after I put two Alen 45i units on opposite sides of my (large) living room/dining area, and one in the bedroom, the air now feels breathable and not at all stuffy when all the windows are closed. I got the VOC filters, though as others have said, that will only do so much. It’s definitely satisfying though when I start cooking and all of the air quality indicators go red on each of the units, but then they kick into high gear and within like 10 minutes the air quality starts to improve quickly, even when still cooking.

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 have an Alen BreatheSmart in each big room and an Alen T500 in the smaller rooms. They are basically silent and work amazingly. Plus you can get set up for filter deliveries every 6 months or so.
