To allergy sufferers (dust mites), what is the best air purifier you've ever tried for dealing with this?
I deal with dust mite allergies and for me the biggest difference came from running a strong HEPA unit in the bedroom nonstop, not just during the day. I’ve used the Blueair 211+ and a Coway model, and both noticeably reduced that morning sneezing and stuffy feeling.

Porkchop refuses to bury his poop, will not acknowledge a stinky turd to save his life while we all die, yet he attacks his turds in the LR and pauses the unit. Why dude?
get an automatic air filter. I can personally recommend the Blueair Blue 211+ Auto, but there are a lot of different ones available and it's hard to go wrong as long as you buy i) a vetted brand that's ii) intended for the room size you use it in. the idea with an automatic air filter is that it run

slightly different direction, and I'm not suggesting you stop your search, but add an automatic air filter to whatever your setup is. automatic air filters run at a low/maintenance level most of the time but kick into high gear when they sense the air quality is wonky. I find out when a cat has poop

Should Blueair's use of ionization be viewed less negatively than the standard ionization tech used by others?

At-home Air Purifiers folks, how is your air purifier holding up??
500 sqft. Blueair Pure 211+. I think it helps, I notice all the dust/gunk it captures when I have to replace the filter every six months.

Has anyone found relief from allergen immunotherapy
My allergies are the predominant driver of my meniere's but I've never done immunotherapy. The keys to address my (mostly pollen and dust allergies) have been: being prescribed montelukast (Cingulair) which apparently attacks the roughly 50% of allergy pathways that antihistamines do not (it attacks

Please just tell me easy as you can
This affects your health, can you ask people to at least store things in sealed tubs or inside boxes of something that can be dusted by the cleaner to reduce the dust for health reasons? And if there is carpet, removing is best, but if not if you can get the cleaner to use a carpet cleaner (the wet

Air purifier for hospice patient
This! I just got my luggable to replace my blue air 211+ and it is quieter running than the Blueair is on the lowest setting. 300sq ft of coverage gives 5 air changes in an hour, I believe. Plus, it's going to cost me $4/month for filters if I change them out every 6 months.

Best Value Air Purifier? (Coway, Winix, Blueair, Shark, Sans, etc)
That's not the point. The original context is my comment: Some people want to avoid this because of possible health effects associated with ionizers or changes in gaseous air chemistry. ...and then you said (in the form of a question) "California’s strict regulations" basically ensure that the "heal
