Airpura R400

Coverage varies by model — check the product specifications above for the rated room size. As a general rule, all units perform best when running below their rated capacity, which reduces noise and extends filter life.

Airpura filter life varies by model and usage. The carbon bed in this unit is rated to last 2–3 years under continuous use in a typical residential environment. HEPA and pre-filters have their own replacement schedules. Replacement filters are available on our filters page. Running the unit below its rated capacity meaningfully extends filter life.

Airpura units use a variable-speed motor, so you dial airflow up or down across a range rather than stepping through fixed settings. At the low end it is quiet enough to sleep beside. At the top of the range it is clearly audible and is meant for clearing a room quickly — after cooking, painting, or on a smoky day — not for running overnight. Most people settle around the middle of the range and leave it there.

No. This unit uses only mechanical filtration — no ionizer, no UV, no ozone generator. It is safe for people with asthma, chemical sensitivity, and other respiratory conditions where ozone is a known irritant. Airpura does build UV-equipped machines, and they are gathered in the UV air purifiers collection — this is not one of them.

Yes. Austin Air and Airpura units are used by patients with asthma, allergies, and chemical sensitivity. The True HEPA captures particle-class triggers and the activated carbon addresses VOCs, odors, and chemical compounds. No ionizer, no ozone — safe for respiratory conditions. For MCS specifically, the HealthMate Plus or Airpura C600 have the most relevant specifications.

Yes. Airpura units are designed for continuous residential operation. The steel-body construction and quality motor components are built for this use case. Most Airpura users run their units continuously at speed 2–3. Continuous operation at a moderate speed outperforms intermittent high-speed runs for maintaining consistent indoor air quality.
