Honeywell - Air Touch P2

lemme share some of the research I did while choosing mine 3ish weeks ago. What you want to look at is CADR. This is measured in m3/hr so ideally you could simplify your search and choose the highest number you find in your range. The Sq ft number is not reliable in Delhi in my opinion. As my budget was also 20K i short listed the following based on what was available at local retailers nearby: 1. Honeywell P2 - 550 CADR 2. Phillips 4221/61 - 600CADR (I bought this) 3. Qubo 1000 - 600 CADR 4. Honeywell U1 - 700 CADR. (most expensive) Most people would be okay with a 550 CADR but my room is tall so i still see the AQI go to 200 at full.

I’ve tried a few and the germ guardians are the best bang/buck. The big Honeywell ones if you have to do a BIG space. We have a Dyson and I don’t love it.

I live in a tall loft with ciment ceilings and it produces a lot of dust. I got a large Honeywell HEPA air purifier and it works very well. The carbon pre-filter can be vacuumed and there is a thick layer of hair and dust every week. The inner filters I vacuum every month and change them once a year.

I use the large room honeywell air purifiers. The one I have now has been running 24/7 for the last 5 years or so and is still trucking along. I use it because my wife and son smoke weed and smoke bothers me. It does a good job getting rid of the smoke and the amount of crap that is on the filter is amazing. I pretty much never have to dust.

Yes, an air purifier helps. The best brand is Honeywell with a HEPA filter. Second is Bionaire with True HEPA filter (purple one), third is Bionaire with the blue filter. Levoit kind of sucks. Don't waste your money on the Pure Enrichment Personal Air Purifier.

Honeywell Hepa Air Purifier is amazing all the time especially post fire. It's saved me.

Honeywell HEPA. Don't buy an electrostatic/ionizer type "purifier" as it creates O³ (ozone) - which is hazardous (and is also a component of smog).

Honeywell HEPA is what I’ve used for decades. Reliable and easy to find their filters.

You can get a HEPA filter air purifier (Honeywell makes decent ones) to deal with PLA and TPU, they dont emit the toxic VOCs like ABS, Nylon and PC, but they do still emit fine particles. Having it enclosed like you do is going to prevent a lot of those fine particles from scattering through the room though so its a big help. As a rule I try to not have my printers in the same room I work, but if you must, that HEPA filter will help reduce the fine particles a lot. For the more toxic materials, absolute best bet is to create a negative air pressure environment while venting outside through a window or port. If you cant or want even more reassurance, running a carbon filter does a lot to help. There are specialized air purifiers for VOCs but theyre not cheap. A really good one you can get is from Heygears, called the GreenPrint Purification Unit. Just know it's specifically for VOCs as it doesn't trap particles, it destroys them (so you still want a HEPA for the fine particles). This air purifier doesnt need filters though, it doesnt trap VOCs like a carbon filter which can become saturated and need replacements. It actively breaks down VOCs, so it just runs indefinitely with full efficiency, no need to swap filters.

Honeywell HEPA air purifiers. I have two: one in bedroom and one in the room where I spend most of my time watching TV, etc. Makes a difference for me.
