How We Evaluate Every Product
Every product we cover is compared on the same four criteria, using published specs and certifications. We don't lab test; these are the things that decide 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
A single "as quiet as 24 dB" figure is usually the lowest fan speed. We compare published decibel figures across speeds, so you know what the cleaning setting sounds like on paper.
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.
