To find the best UV air purifier, you’ll need to examine a list of criteria to determine what is most important. We recommend the best UV air purifier with a minimum 3-stage filtration system, consisting of a pre-filter, true HEPA filter, activated carbon filter, and UV-C light. Some might argue that an air cleaner is better than an air purifier. Nevertheless, all work to battle airborne contaminants as small as 0.3 microns with some medical-grade filters (e.g. Hyper HEPA) capable of neutralizing particles as small as 0.003 microns. Other areas of consideration include square footage rating, CADR (Clean Air Delivery Rating), and a full set of digital controls including multiple fan speeds, Sleep Mode, and a real-time air quality monitor. these are some of the features that make your purifier a top-rated air purifier.
After analyzing hundreds of reviews, we’ve determined that the Pure Enrichment PureZone Elite 4-in-1 UV Air Purifier is the best UV air purifier you can buy. Keep reading about this and our other top picks to learn more about choosing the best air purifier for your needs.

For a unit that only needs a quick vacuum of the HEPA filter without a filter replacement, check out the best air purifier with a washable filter.
How We Decided
We explored efficiency, versatility, and digital controls to determine the best UV air purifier to buy.
Our preference is for the best air purifier with UV light to carry a 3-stage filtration system that uses a pre-filter, true HEPA filter, and activated carbon er. All work to neutralize airborne pollutants such as pollen, mold spores, dust, bacteria, and viruses. We are also big fans of UV-C lights for an additional layer of protection battling microorganisms that can get past a filter. Additionally, the best UV air purifiers should carry a minimum square footage rating of 350 square feet with excellent CADR numbers (smoke, pollen, dust), indicative of how fast air refreshes throughout the room. The higher the CADR number, the more air changes per hour.
Versatility and digital controls with UV air purifiers are very important. Look for UV air purifiers with a full set of digital controls that make it easier to adjust fan speeds based on put. A minimum of three fan speeds is a great place to start. Additionally, look for Sleep Mode, which allows dimming of lights and noise levels at the lowest setting – great for nurseries and bedrooms. Real-time air quality monitoring with color-coded LEDs or Bluetooth/WiFi app compatibility is a plus, but not offered by most of the picks on our list. And if you are in a new home, you may want to check out air purifiers that work on VOCs and formaldehyde to help prevent future problems associated with those gases that are common in new furniture and some paints, among others.
Best UV Air Purifier Buyer’s Guide
The Most Important Features to Consider
Look for UV air purifiers that carry a generous square footage rating and solid CADR scores for pollen, dust, and smoke.
- The higher the CADR scores, the faster air is refreshed in a room, and the more air changes per hour for a truly refreshing clean.
- Efficiency also means a minimum 3-stage filtration system that uses a pre-filter, for larger particles (e.g. pet dander), a true HEPA filter for ultrafine particles as small as 0.3 microns, and an activated carbon filter that works its magic on smoke, odors, and gasses.
- UV-C lights are the cherry on top, killing microorganisms such as bacteria and viruses much smaller than 0.3 microns. In that case, read our Silveronyx Air Purifier With a True HEPA Filter review for a unit with UV-C and more.
- It’s a good idea to keep efficiency top of mind as you shop through the different types of air purifiers. For starters, you can read our comparison of a PCO air purifier vs HEPA to see which is best for your home.
We’re big fans of UV air purifiers blending in well with the environment, preferably with slim profiles to fit beside nightstands or entertainment centers or compact sizes to sit on a tabletop. Airflow should also be 360° distributed instead of a bottom-to-top concept for more even distribution of intake and release in a room, especially in open areas.
- Digital Controls
Our preference is for the best UV air purifiers to carry a full set of digital controls. Multiple fan speeds should be included at a minimum, followed by Sleep Mode, Auto Mode (auto adjustment of fan settings based on output), and real-time air quality monitoring that uses color-coded LEDs to indicate good, fair, or poor levels.
