Best praise vs top criticism for Medify MA-25
“I used the Blueair, and it just stopped working. Too much of a headache. Don't suggest those. Then I bought the Medify MA-25, and it's the best thing ever! I've had it for more than a year now, and not a single problem yet. It's just amazing! And the best part is that it's way cheaper than the Blueair. I really couldn't be happier with this. Highly suggest it! You can find it on amazon.”
“MA-25 is not a large unit. You're trying to clear the air in a 500sqft. area with a unit that can only do 2 effective air turnovers on 400sqft. on its highest setting. You want a unit that can do 4 turnovers on that size, and those are very pricey. The correct way to purify that space would be two units, one on either end, and both significantly larger than the MA-25. Or a garage dust extractor, which isn't HEPA but does the job, and mounts to the ceiling and has ridiculously high air flow.”
