These seem to easy. How do we know crboxes are effective?

I have an Alen Breathesmart 45i air purifier. We switched locations to a smaller more sealed apartment after the worst of the smoke hit. I also have an air monitor that gives me pm2.5 readings. The New place was pretty bad when we first got there. The 45i was doing a decent job of lowering the indep

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

Moving from Phoenix to Portland/Salem.

The window AC units don’t filter fine particulates at all. But if you get like an Alen air purifier, it will. But that will also add to your electricity cost, assume another $1.50 a day for the 45i unit which I ran non-stop.

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

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.

Baby allergies due to wildfires

We live in Idaho where the smoke is super bad and I just replaced our air purifier filters today. It’s helped but I’m considering buying a few more purifiers. We have the Alen breathsmart ones. You should also replace your HVAC filter, make sure your thermostat is set to recirculate air and that the

After these category 5 haboobs this week, fine dust is literally inside my window sills

Alen Air Purifier is what you need. Start with the 45i or even the 75i for a big room. Game changer.

Selling empty house and getting complaints of dog smell

I think they mean an electronic filter added to your HVAC system that cleans air going thru it. It has a light source that cleans the air. Periodically have to get a new light bulb replacement. I have the electronic air cleaner in my house connected to HVAC but we still bought an ALEN Breathe Smart

Winix C610 vs BlueAir Signature?

Winix by a mile. I wouldn’t pay more for a blueair. Also the c610 is undersized for your needs. Look at the WX100 or Alen 45i or 75i Keep in mind, a lot of shady companies (like blueair) “claim” a certain square footage coverage. But that coverage is 1 air change per hour. If you actually want to pu
