Frequently asked questions
What does a good air purifier cost in the United States?
The models in our ranking run from about $43 to $749 today. We show the lowest verified price of the day per model, shipping included, before sales tax.
How big an air purifier do I need?
Match it to the size of the room. Each model in the ranking is grouped by the room size its maker states, and the lists keep a model out when it states none. A common rule of thumb is a clean air delivery rate (CADR) of at least two thirds of the room’s floor area in square feet, for a ceiling of 8 feet.
What is the difference between HEPA H13 and True HEPA?
Both are high-efficiency filters. True HEPA is the American name for a filter that catches 99.97% of particles of 0.3 micrometres, and H13 is the European class for 99.95%. We read the class the maker states and do not treat a filter called HEPA-type or HEPA-like as either.
Can an air purifier make ozone?
Some can, mostly models with an ioniser or a plasma feature. California limits ozone from indoor air cleaners to 50 parts per billion, and the CARB certification shows a model meets that limit. Our asthma filter leaves out models whose ioniser cannot be switched off.
How often do you update the prices?
Every day, at every store we follow. We read the prices from the stores’ own product feeds and web stores. We check them for errors and keep them, so every product page shows what a price did over the last 90 days. We only call a discount real when the price also sits below the level of the preceding 30 days. We link to Amazon too, but show no Amazon price until we read it through Amazon’s own API. Until then the price is on Amazon itself. Per store: how and how often
Where we check prices
We read prices every day at most stores, from their product feed or web store. We check them for errors and keep them, so you can see what a price did over the last 90 days. We link to Amazon too, but show no Amazon price until we read it through Amazon’s own API. Until then the price is on Amazon itself.
