BreatheSmart 45i

Yeah, I could get 2 x 45i for the same price as 1 x 75i at current sales, and the 2 x 45i would give me more CADR with less noise, since 2 x 45i at speed 1 gives a CADR half-way between speeds 2 & 3 with 1 x 75i (and better coverage, since I could put them at two different locations in my room). Spe

I'm sticking with Alen and their filters. I like the lifetime guarantee. I will watch what happens with this lawsuit though. FYI, it's only the 45i and flex that are being addressed in this class action suit, not sure what that means, but I would think they would include all models if they had teste

Purifiers under 200 wont do much for odors unfortunately. Or not for very long. You need thicker filters with black carbon pellets -these absorb odors. The normal white filters in most purifiers just capture particles. Does nothing for odors. Under 200 dollar units will fair chance have a thin carbo

I definitely do not want any cats to be harmed. But you could try gluing some wooden poles/stakes (soft/flat or rounded on top) and just glue them on top so a cat can't sit there. One easy way is a cheap 20 dollar plastic table furniture, as they come with like 8 white (or whatever color) plastic sp

I run my Alen on high. It's still very quiet. Is it not prudent to not comment a lot on a unit we don't have much first hand knowledge on, yes ? Alens have a lifetime warranty. Quiet, + energy efficient. And great for odors+VOCs. I don't know (any ?) other brands units that offer a lifetime warranty

Levoits are great. I would not get the shark. Winix is also great, as far as I know. In terms of the filters, I havent seen testing or anything on the different filters. I use the pet hair ones when I can find them cheap. They should be a little better at getting pet hair/dust maybe. So for same pri

For VOC's + odors Austin Air is very good but you would need to pay about 750 (they might have a cheaper one ?). That's one of the best, and probably worth it for your health imo. As you aren't even sure what your triggers are possibly, you want to get something very good. So those have a very large

Did not even consider the voltage difference. Was contemplating cutting the cord and patching in a standard US 3-Prong. Super tempted to buy a used Alen BreatheSmart 45i or FLEX as they seem to be very similar. Honestly, I like that the Alen VOC/Smoke filters it have a decent amount of Carbon in the

Re: dust, this is frequently asked. Air purifiers aren't good at removing visible dust as it's large and heavy compared to something like PM10, PM2.5, or PM0.1. See the sticky post at the top of this subreddit and our FAQs wiki page entries: I need an air purifier for dust. What should I buy? Why is

Alen Air all the way. Tried just about every purifier sold From Target, Walmart, Kohls, Home Depot, Best Buy, Lowe’s, Menards… Almost all went back Shark used to be good, but their newer filters smelled like chemicals and they were super loud. Germ Guardian was ok, but quality dropped. Dyson is a jo
