The Levoit True HEPA Air Purifier keeps airborne contaminants out of your home with a three-stage filtration system that removes 99.97% of 0.3-micron particles. The True HEPA filter traps fine particles and allergens, and the high-efficiency activated carbon filter absorbs and decomposes odors. The Levoit Core-RAC is for bedrooms and large rooms, covering up to 219 sq. Auto mode adjusts settings automatically to work efficiently or at your preferred quietest setting, while a sleep mode dims the display and adjusts the purifier to its quietest settings.
This purifier has five different filters, one being a True HEPA filter and another a customizable option. With the customizable filter, you can choose an option that homes in on germ defense, pet allergies, toxin absorption, or odor removal, depending on your particular concerns. With so many filters, you can expect to do a lot of unwrapping before you begin using your purifier, but all those filters work together to get the job done.
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 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.
Again, a HEPA filter is going to do the trick for most common irritants and odors, including pet hair and dust. But if you live in a smoker’s house, look into something more robust. In conjunction with this, the more high-tech air purifiers can employ an extra line of defense. Some models use an optional UV light that renders many micro-organisms sterile, and an activated charcoal levoit filter filter that can actually pull in and neutralize toxins through electrostatic attraction. There are also models that can ionize incoming particles, which are then sucked in by metal plates or other treated substances. This air purifier comes with the cylindrical design concept, together with the same smooth flowing curves, and same 360° air intake grill like the Core 300 model.
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.
A year later, with those same filters—far past their recommended six-month replacement schedule—the numbers barely dropped, reaching 99.1% and 98.0%, respectively. Those results make the Blue Pure 211+ one of the most efficient air purifiers we’ve tested, as well as one of the most consistent on different settings. And the fact that it maintained its high performance even on significantly overused filters gives us confidence in its long-term performance. If you need to purify the air in a seriously large space, we recommend the Blueair Blue Pure 211+. It’s extremely powerful, delivering our recommended 4 ACH in spaces as large as 650 square feet (assuming an 8-foot ceiling). That means it can clean the combined living areas of many open-floor-plan homes.

Its compact and portable build allows you to filter out any unwanted smells or toxins from essentially anywhere in your home. Plus, it offers two night light settings and operates quietly to easily create your dream sleep experience. Air purifiers equipped with HEPA filters specifically can reduce particle concentrations by up to 85%, according to the EPA.
The only safe use of ozone generators is in unoccupied rooms, utilising “shock treatment” commercial ozone generators that produce over 3000 mg of ozone per hour. However, it is not healthy to breathe ozone gas, and one should use extreme caution when buying a room air purifier that also produces ozone. This compact Levoit air purifier can be hooked up to Alexa and voice-controlled. You can also use the smart remote control to adjust the fan speed or just leave it to Auto Mode to increase the indoor air quality most optimally. The first number in the noise level range is the noise level for the low fan speed setting, and the last one is for the high fan speed setting. Usually, it’s recommended to run the fan at high speed during the day and at a low-speed setting at night.
