The answer — one pick, priced

Levoit Vital 200S‑P
$80 under your budget
HouseFresh's best for most people — 249 CFM PM1 buys the same honest 390 sq ft as picks costing $100 more, and its pelleted carbon genuinely kills pet odour.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It is too loud for a light sleeper. 41-58 dB against the Mighty2's 19-50 dB: on anything above the lowest speed you will hear it from a pillow. This is a living-room purifier that happens to be cheap, not a bedroom one.
Dealbreaker? Runner-up №2 runs 19-50 dB for $100 more ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you need a portable or desktop air purifier for personal space under 100 sq ft
- you need whole-house air purification integrated with HVAC system
- you primarily need humidity control alongside air purification
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Levoit Vital 200S-P is right for you
It avoids every trap below — and for anyone, under $250, it is the pick because it delivers:
The square footage is a lie
Manufacturers quote coverage at 1 air change per hour; the EPA and AHAM want 4-5 ACH for allergy, asthma and wildfire-smoke use. Divide the box figure by 4-5 — a 1,800 sq ft Coway Mighty2 is a 390 sq ft purifier. Every room number here is already converted.
Filters outrank the sticker
Annual filter cost runs $40 to $195 across this field. Over three years the cheapest pick lands near $330 all-in and the dearest near $1,930 — a 6x spread the purchase price never shows.
Ionizers you cannot switch off
Ionization is a health caveat, not a feature. The Blueair Blue Signature's HEPASilent ionizer cannot be disabled (3 ppb ozone, UL 2998 certified); the Coway AP-1512HH's bipolar device can be, and should be. Treat "ionizer, not defeatable" as a spec, not a footnote.
