A particle-filtration unit built around HyperHEPA, which captures particles far finer than standard HEPA, with a small gas stage. What it is built to do.
The IQAir HealthPro Plus is built around HyperHEPA, a filter rated to capture 99.5% of particles down to 0.003 microns — about a hundred times finer than the standard HEPA rating — at around $899–950. It is designed for ultrafine particles: wildfire smoke, mold-related particulate, biological contamination.
It is not built as a chemical-removal unit. Its V5-Cell gas stage carries about five pounds of media, against the 26–39 pound carbon beds of dedicated carbon purifiers, so where fragrances, fumes and VOCs are the main trigger it is a particle unit that would sit beside a carbon unit, not replace one.
The Institute sells nothing and rates nothing; this page reports what the unit is, how it is built, and what it is designed to do.
This page profiles one brand in reporting voice: what the unit is, how it is built, and what it is designed to do. It does not rank units or name one to buy. How reactive you are, your dominant triggers and your room size all change what fits; the Air Filters & Purifiers guide walks the general decision before naming any product.
HyperHEPA rated 99.5% at 0.003 microns. The V5-Cell MultiGas stage adds roughly 5 lb of gas media. The design is aimed at rooms where ultrafine particles are the problem — active mold, a water-damage history, smoke.
Five pounds of gas media is not a deep carbon bed. The housing is plastic. The gas cell’s media is impregnated with permanganate, so the same material fact stated on other impregnated-media units applies: someone who has reacted to treated media before has that to weigh. In a chemical-first room the design pairs with a deep-carbon unit rather than standing alone.
The unit comparison is on the Air Filters & Purifiers guide, and the Mold & MCS page if mold is the reason for buying.
