How We Evaluate Every Product
Every product we review is measured against the same four criteria — the things that actually determine whether it works for your space.
CADR & Room Coverage
How much air can it actually clean, and in what size room? We map CADR ratings to real-world room sizes so you know if it fits your space.
Noise Output
Decibel ratings don't tell the whole story. We evaluate noise quality and whether you can sleep, work, or live with it running.
Filter Quality
HEPA isn't all the same. We look at filter grade, what it actually captures, and how long it lasts before replacement is needed.
Total Cost of Ownership
Purchase price, annual filter costs, energy consumption. We add it all up so you can compare what you'll actually spend over two years. This number flips the recommendation more often than you'd think.
