I’ll pay you $10 if you can recommend air purifiers and their placements for this ~2,500 square foot house!

If you’re dealing with dust, honestly I wouldn’t even look at a purifier yet. You need a vacuum upgrade. Dust particles are too heavy for any purifier to suck in from across the room. Check out r/vacuumcleaners. But Something corded and bagged (yeah old school) but it will make a monumental differen

PC fan purifiers vs HEPA for allergies

Well whichever has higher CFM will be better for your allergies,.if both Hepa 13 + Merv 13. But that will also use more energy. So those are two opposing things. If your potential PC box has higher CFM then allen with Merv 13+ filters, then that might be better. But if you run it on low or medium to

How long for new-filter smell to dissipate on the Coway Airmega ProX?

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

ALEN Air purifier, filter replacement.

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

Anyone with experience with alen air purifiers.

I’m using Alen 45i and 35i in our home and they work great. we have 2 cats and these machines remove any pet and cooking odors. filter needs to be replaced once a year. Having an app makes it handy to check or change settings as needed, also has a schedule option. good machines for the money.

Looking for air purifier for cat smell

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

What's the best air purifier you've tried for Pets? Any recommendations?

You need a multi level approach. I use the Alen breathsmart air purifier. I would highly recommend getting an enzyme cleaner. That’s been the real game changer for us. I use the Allersearch ADMS Anti-Allergen line. I have the spray, laundry detergent, and floor cleaner. It helps tremendously. I feed

Dyson Purifier Big+Quiet Formaldehyde for hayfever

Good brands with affordable units are Winix, Levoit, Coway, Alen, and many more. A Levoit Core 600 for instance is around 280 dollars and does 350 range CFM...almost double the Dyson for 1/4th the cost. Winix + Coway have great units too. (Coway used a fungicide/pesticide on the filters for antibact

My first air purifier for my living room! Help!

I would look into Alen 45i Flex, or units from Winix, Levoit, or Coway. Alens are quiet and good for both VOCs + particulates, with their best filters, and come with a lifetime warranty if you stay in the filter replacement program. (I think 90 bucks every 9 or 12 months, your choice.). However if y

Allergies bad … impulsively purchased this purifier

Right, so I don't know your budget, but I believe a CR Box with 400ish CFM would give you around 5 air changes per hour...for borderline excellent air. (4.8 is good, 6 is excellent.) So you want to try to get I believe around 400 or even 500 CFM if you want excellent. A 280 dollar Levoit Core 600 do
