Air purifiers capable of cleaning the air in 2500 square feet areas are rare gems. Not every machine is capable of filtering the air in rooms of over 1000 sq. ft., let alone 2,5 times larger areas! Many of air cleaner that are advertised for 2,500 sq. ft. areas does not have enough power and airflow to cover such large spaces.
However, there are a few solutions for a reasonable price at the US market today. So here I review my 3 best air purifiers for 2,500 sq. ft. areas that I consider investing every penny into.
Smart Health Blast: Best Pick for 2500 Sq. Ft. Areas
Smart Health Blast is a portable HEPA air purifier designed for extra large rooms, offices, public and commercial areas up to 2500 sq. ft. And in some case it can also be used in an area of 5000 square feet!
But what makes this purifier the best option? Well, a lot of things. To name a few:
- It uses the extremely large, true HEPA medical-grade filter H13. This air filter captures 0.3 micron particles at 99.97% efficiency. It means tiny dust particles, allergens, bacteria and even viruses are captured by this extremely powerful machine.
- The HEPA filter has a long-lasting lifespan of almost 2 years before it will need a replacement (check price).
- In addition to the HEPA filter, a large 9-pound and high-quality Activated Carbon filter (dimensions 44.9 x 0.04 x 21.3 inches) absorbs odors like smoke, including cigarette smoke, pet, kitchen, bathroom and body smells. For an area filled with people and odors this is the best solution to clean the air from various unpleasant smells.
- The charcoal filter has also a log lifespan of 18 months (most carbon filters run for 6 – 9 month max) before you have to buy a replacement for it (check price).
- Extremely high CADR rating of 1360 CFM at high speed. The Smart Health Blast delivers 4 air changes per hour in a 2500 sq. ft. area with 8 ft. ceilings, which is good news for people with allergies as they require 4 ACH to be delivered by an air purifier to feel any relief.
- The area coverage expands to 5000 sq. ft. if 2 air changes per hour is enough for the place.
- Extremely low noise levels: 29 decibels at low speed and only 48 dB at high speed. This level of sound is comparable to moderate rainfall or an average home sounds.
- Does not release any ozone.
- Certified by CSA, CARB and UL.
All in all, the Smart Health Blast HEPA air purifier is the best you can get for the price. It offers a unique cleaning solutions for medical facilities, large homes, offices and other public and commercial areas.
OdorStop OS2500UV Professional Grade Ozone Generator for 2500 Sq. Ft.
The OdorStop OS2500UV is a professional grade ozone-generator and ionizer for 2500 square feet areas. Compared to the Smart Health Blast, the OdorStop’s primary air filtration is a process called ionization instead of HEPA filtration.
This is the process when atoms or molecules are converted into electrically charged atoms or ions (molecules) by gaining electrons. By gaining them, the molecules also gain weight and this causes them to land of various surfaces that include floor, curtains, tabletops and so on. After that the area can be cleaned.
The OdorStop OS2500UV also uses the washable filter to help you get rid of the fallen particles. However, it doesn’t have much power and the fan airflow is capped at 110 CFM, so it will take some time to fully clean the 2500 sq. ft. area.
However, since it produces unsafe amount of ozone, the machine should be run in an unoccupied area. After the air cleaning is done, wait 30 minutes before entering the space. It is also not eligible to work in California due to CARB limitations. However, it is a good pick for basements, offices, hotel suits and other places which require a powerful ionizer and ozone generator to remove heavy and musty odors.
Any OdorStop unit also comes with a 5 year warranty and is almost silent while running.
