10) Airpura UV700 – Top-notch Solution for Mold Purification (>$800)

Founded in 2004 in Quebec, Airpura has built its reputation on one guiding principle: air purifiers should not add contaminants while removing them. The Airpura UV700 is the direct upgrade to the UV600, carrying forward the same proven UV-C filtration stack with a quieter, more powerful 635 cfm motor. For anyone who needs commercial-grade mold and virus protection at home, this is the air purifier to have.

You can trust this air purifier with the most advanced UV-C filtration system Airpura has ever built:

• Additional filters – The Airpura UV700 uses a poly pre-filter to trap large particles like dust and pet hair, protecting the main filters and extending their lifespan. It can be vacuumed clean and should be replaced every 12 months.
• True HEPA filter – A medical-grade True HEPA filter with 40 sq ft of filter media captures 99.97% of airborne particles as small as 0.3 microns, including mold spores, bacteria and viruses.
• Activated Carbon filter – A massive 18 lbs of 100% coconut shell activated carbon adsorbs chemicals, VOCs, gases and odors (including mold odors) with exceptional capacity and longevity. Replace every 24 months.
• UV-C Light filter – An 18W germicidal UV-C lamp destroys the DNA structure of viruses, bacteria and mold spores that survive filtration – the most powerful UV-C lamp available in any residential air purifier on this list.

The Airpura UV700 is a clear upgrade over its predecessor, the UV600. The same trusted 4-stage filtration architecture is retained, but with a significantly more powerful and quieter motor that delivers greater airflow without increasing noise. Its 360° perforated steel housing draws in air from all directions, ensuring thorough, whole-room purification at all times.

With a manufacturer-published CADR of 635 cfm, the Airpura UV700 has one of the highest fan power ratings of any residential air purifier available today. It is recommended for rooms up to 2,500 square feet, running as quietly as 30 dB on its lowest setting – a near-silent operation that makes it equally practical for bedrooms and large living spaces.

However, the Airpura UV700 does not include a Smart Sensor or any automatic features – fan speed must be adjusted manually. This is worth bearing in mind at this price point. That said, for anyone dealing seriously with mold, mildew and airborne viruses, no other air purifier on this list combines this level of UV-C power, carbon mass and airflow in a single unit.

In our air purifier ranking list, the Airpura UV700 ranks C. Even so, its 18W UV-C lamp and massive 18 lbs carbon filter make it the most purpose-built air purifier for mold and virus control on this entire list.
