You can buy Levoit filter replacements directly through its website, or through third-party retailers. Here at The Spruce, we want to ensure we fully stand behind every product we recommend and that when we say something is the best, we mean it. You might have noticedThe Spruce Approved badgenext to the products on this list. Every product with this badge has been rigorously tested in person and carefully selected by our expert team of lab testers and editors. In most cases, we buy all these products ourselves, though occasionally, we get samples provided to us directly by companies.
We ran our original test model for two years without replacing the filter, and it still performed just as well in our follow-up test as it did on day one. We ran our second test model 24/7 for four years, and levoit purifier again we saw no change in performance, noise output, or reliability. It isn’t a perfect approach, but considering the multiple variables involved, it is the most accurate way to compare different purifiers.
Products that claim to be “HEPA-type”, “HEPA-like”, or “99% HEPA” do not satisfy these requirements and may not have been tested in independent laboratories. Polarized-media electronic air cleaners use active electronically enhanced media to combine elements of both electronic air cleaners and passive mechanical filters. Most polarized-media electronic air cleaners use safe 24-volt DC voltage to establish the polarizing electric field. As airborne particles pass through the electric field the polarized field re-orients the particle to adhere to a disposable fiber media pad. Ultra-fine particles that are not collected on their initial pass through the media pad are polarized and agglomerate to other particles, odor and VOC molecules and are collected on subsequent passes.
ProductProcedure for resetting the filter reset indicatorLevoit LV-H126This one doesn’t have an air quality indicator. It has a filter reminder wheel that you can use to track when it’s time to change your filters.Levoit LV-H128Plug in the air purifier, but do not turn it on.

Many also have night modes, which activate a quieter operation or dim digital display lights to create a better sleep environment. Several of our picks, including our “best for pets” and “best features” options, theRabbit Air Minus2 Ultra Quiet Air Purifierand theBissell Air400 Professional Air Purifier, respectively, offer silent modes. In long-term testing, we found that these settings made the purifiers’ operation virtually undetectable. Note that if your air purifier starts to make more noise than you consider typical, its filters may need to be cleaned, replaced, or readjusted. CADR stands for clean air delivery rate and refers to the volume of air, in cubic feet, that your air purifier can clean per minute.

The Mila works with multiple filters, some of which contain significant amounts of activated carbon for VOC removal. For particulate removal, all the filters are rated at the European HEPA standards H12 to H14. The higher-rated filters do restrict the airflow somewhat, however, which is why the Mila’s maker levoit air filter recommends them for bedrooms or small living rooms rather than large open spaces. If you simply need to remove particulates from your air in a large space, the Blueair Blue Pure 211+ is easier to live with—it’s quieter, smaller, and better looking, which is why it’s our main pick for large spaces.
