75i

Thanks for that info. I did look up sound pressure levels and answer online answer was it was the same as decibels, although that might not be accurate. I may try the Everest Air. Surprised to hear that Coway Pro X is quiet at that higher cfm. Will check it out. I recently purchased an Alen 75i from

You may want to investigate a whole house air filtration system if you indeed have the budget. Otherwise your options are basically something like AirPura, it filters both air and uses large amounts of carbon to get rid of smells.. https://www.airpura.com/ An alternative would be something like the

There's literally only one aiir purifier that's quiet and it's the Alen Breathsmart 75i. I've had dozens of different brands and that's the only one that is whisper quiet even on full blast, literally nothing else compares. They aren't cheap but if sound is a concern and you want a air purifier that

I have the 75i which is rated 351 cfm for dust, luggables Xl-7 Ultra is 401 dust, and 450 pollen. I'm happy with both of them. Alen says either 7-10 months for carbon filters or 12-15 Mos for the pure hepa. I've owned for 3 mos and the indicator shows nearly 50% used. If that's the case it's not goo

I have an Alen 75i, its 100 cfm on speed 1 and 185 cfm on speed 2. I cant hear speed 2 unless I put my head right over it. And when you need the cleaning power it's 375 cfm on speed 5 which still isn't loud. Might be too expensive for you, but they do sell refurbished at Alen website and I've seen t

Oops sorry I misread where you said budget was $250! I'll leave this here just in case it's helpful for someone else down the line. Looked up the C545. Claims it cleans 436 ftsq every 15 minutes (4x per hour). That would be on high speed. There are a few other purifiers that have better cleaning per

Look at creating positive pressure - easiest way is a fan in a window blowing air inwards. This should be your first plan of attack imo. As for purifiers, you’ll want the most carbon you can get. For your budget look at Alen 75i + their VOC filter. There are others with more carbon but they’re $$$$.

I feel like I have the flu every time I visit Utah, groggy in the morning & headaches, poor sleep, etc. Brought my air purifier with me from home & I feel cured! I have an Alen 75i. Sounds like there are more inexpensive options that work great. I lent it to my Utah neighbor because her new born was

Check out Alen. 45i or 75i. Just know that no purifier is going to do much about visible dust. Just the microscopic stuff.

If you want to buy off the shelf: Alen 75i (or two) with their VOC filter. Should be right on budget. Although I do believe they have commercial units as well. Check their website for commercial pricing.
