What's New

We update PureAirScout constantly — new reviews, refreshed guides, corrected figures. This is the public record of that work, newest first. Spot something wrong? Tell us and it lands here when we fix it.

July 2026

• PureAirScout launches with research-based reviews of HEPA air purifiers from budget room units to premium large-room machines.
• Free calculators go live — room-size to CADR, air changes per hour, running cost, and true filter cost of ownership.
• The Air Purifier Finder matches a purifier to your room, your air, and your budget — with the top alternatives, in about two minutes.
• Transparent scoring — every review carries a six-part score and states its sources.

How to read our dates

Every review and guide shows an "Updated" date in its byline. That date moves when we meaningfully revise the page — not on cosmetic tweaks — so it means what it says.
