HEPA Air Filters filter 95% for aerosols of diameter between 0.25 and 1.0 μm and nearly 100% for those with diameter larger than 2.5 μm — the most common ranges for viruses such as SARS-CoV-2. By keeping the air clear of other pollutants and allergens, air purifiers help your respiratory system remain healthy and better protect you from infection.
Levoit True HEPA Air Purifier is an affordable air filter with Advanced 3-Stage Filtration System: The Pre-Filter, True HEPA Filter, and High-Efficiency Activated Carbon Filter capture allergens, pet hair, dander, smoke, mold, odor and large dust particles, in addition to removing 99. 97% of airborne contaminants as small as 0. 3 microns. Ultra-Silent Operation: Filters the air with the lowest noise level as quiet as 25dB for a restful and soothing indoor environment, helping you sleep deeply.

For pricier options we have Molekule, which feature Photo Electrochemical Oxidation (PECO) nanotechnology to destroy viruses, VOCs, allergens, bacteria & mold.
Developed over 25 years by research scientists, PECO is an innovative technology that utilizes free radicals—the same radicals used to destroy cancer cells—to break down pollutants at a molecular level, including VOCs, bacteria, mold, viruses, and allergens. By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than the standard filters must meet to qualify as HEPA.
Molekule Air and Air Mini are easy to control using its one-touch interface. For added convenience, you can connect it to your WiFi and control it remotely using the iPhone or Android app.
Molekule Air Purifier for larger rooms and the Molekule Air Mini+ Purifier for smaller rooms.
