Is an air purifier worth it?
Yes air purifier is very well worth it, especially if you can [get a good air purifier](https://www.reddit.com/r/homeowners/comments/1oneci4/the_best_air_purifier_for_home_to_buy_now_do_you/) like the Coway Air Purifier or the Blueair Air Purifier, think those are the best

The Best Air Purifier for Home now? Have you noticed a huge difference since you started using them?
I still like the Coway AirMega 200M (same as the AP-1512HH). It’s not the quietest at higher speeds, and it’s not tiny, but it moves the air and filters very well. There’s a reason it’s long been the top pick of Wirecutter. If you want some more style, the various BlueAir models, especially the Pure line are very nice and also work well. They’re a bit expensive though. If money is no object, Austin Air makes some highly regarded machines. In general, UV and ozone are gimmicks. The biggest thing to look at are the CADR ratings. Higher numbers are good, they mean the unit is delivering more filtered air quicker. Always check replacement filter prices, often a good deal on a machine means they make money on selling filters.

The REAL best air purifier - I HATE DUST!
I can also vouch to BlueAir customer support. I bought a second-hand air purifier and found out it was malfunctioning (weird noise coming from the motor). I sent over an email to suppport after having asked the seller for the receipt and they were able to send a new unit to me even out of warranty. Well, what happened to that unit? IT GOT STOLEN FROM MY PORCH. So I contacted BlueAir again. And they sent me a new one, AGAIN! As to the actual purifier, it's a 311i Max, it looks great and seems to work fine too. Have noticed less dust in the room it's at. It's pretty powerful but my rooms are all closed off from one another so doesn't help much for other rooms, however.

The REAL best air purifier - I HATE DUST!
I have a blueair 211i and 2 311is and I love them. I have noticed a significant decrease in dust and allergy symptoms. I recommend getting at least one for the bedroom and one big one for any open areas.

The REAL best air purifier - I HATE DUST!
I have a BlueAir 211i max and I'm very happy with it. It's great with dust and pet dander and also excellent for smoke—I live in an area often affected by wild fires.
