The conventional choice on our air shelf: a True HEPA purifier from the company that has made airflow machines since 1945, with the filtration numbers the boutique options on this page decline to publish.
Our air coverage has developed a hole in the middle. Airdog sells a $1,199 washable-plate machine whose performance no third party has verified, and AirTulip sells a $4,490 headboard with no published airflow figure at all. The PCO575DC is the opposite proposition: a conventional True HEPA purifier, rated to remove up to 99.97 percent of airborne allergens down to 0.3 microns, in front of a carbon stage for odours and gases, moved through the room by the circulation engineering Vornado has built fans around for eighty years.
The stated coverage is up to 258 square feet, which is a real bedroom or office rather than an open-plan floor. Sensors watch dust and odour levels and adjust the eight-speed airflow automatically, there is a sleep mode and a control lock, and filter indicators tell you when the consumables are actually spent rather than leaving you to guess.
Two things belong in the honest column. First, Vornado layers a titanium-dioxide and UV stage it says attacks viruses, bacteria and VOCs that HEPA cannot capture; that is the brand’s own claim, carries the brand’s own asterisk, and no independent test of it is published, so buy this machine for the HEPA and the carbon and treat the rest as a bonus you did not pay for. Second, Vornado publishes no CADR for it, which is the one number that would let you compare it against other purifiers head to head; the 258 square foot rating is the brand’s own basis.
The warranty is five years, which Vornado calls industry leading and which is, at minimum, five times what the boutique air brands on this page offer. At $399.99 it is the least expensive serious purifier we card, and the only one whose filtration grade is a published standard rather than a proprietary story.
A bedroom or office up to about 258 square feet where you want standards-grade HEPA filtration with automatic operation, from a brand whose parts and filters will still be purchasable in a decade.
You need whole-home coverage, in which case a ducted or multi-unit approach beats any single tower; you want a comparable CADR number before buying, which Vornado does not publish; or the recurring cost of HEPA and carbon replacements is the thing you are optimising away, which is Airdog’s washable-plate argument.

Vornado PCO575DC - buyer FAQ
How much does the Vornado PCO575DC cost?
It is $399.99 in a single configuration, verified 21 August 2026 against Vornado’s own store data, with the product in stock and purchasable that day. Replacement HEPA and carbon filters are sold separately, and the built-in indicators tell you when each is actually due rather than running on a fixed timer.
How big a room does the PCO575DC cover?
Vornado rates it for rooms up to 258 square feet, which suits a large bedroom or an office. That figure is the brand’s own basis: no CADR is published for this unit, so a head-to-head airflow comparison against other purifiers is not possible from the published specs alone.
Does the UV stage in the PCO575DC really destroy viruses?
That is Vornado’s claim, not ours. The brand states its TiO2 and UV stage attacks viruses, bacteria and VOCs that HEPA cannot capture, and marks the claim with its own asterisk. No independent test of that stage is published, so we recommend the machine on its True HEPA and carbon stages, which follow published standards, and suggest treating the rest as unproven upside.
What warranty does the Vornado PCO575DC carry?
Five years, which is long for the category: the boutique air devices we cover typically carry one year. Vornado has been building airflow machines since 1945 and sells filters and parts directly, which matters for a product you expect to run daily for years.
