HVAC filters




Puremaxx is a wholesale distributor and manufacturer of all types of HVAC filters. We have 2 facilities in Knoxville TN with over 60,000 square feet of HVAC filters from standard pleated filters to high grade HEPA filters for cleanroom and hospital applications, making us one of the largest air filter distributors in the southeast US! We carry a massive inventory of MERV 8, 11 and 13 filters pleated filters along with many final filters and media rolls!


Our in-house HVAC system filter manufacturing capability allows us to have the fastest turnaround times on non-standard size pleated filters and polyester rolls and cut pads. Our customer base of mechanical contractors and facility maintenance crews benefit from many of our customized offerings such as, getting orders sorted and labelled to speed up the installation process with no filters left to store. Just in time, job-site deliveries also remove the need for filter storage. COVID 19 has put filtration front and center and our ability to provide higher quality filtration quickly has helped many facilities protect and improve their indoor air quality.



MERV 8 to 15-Mini Pleats-Carbon Pleats-Steel Frame Pleats-1″ thick to 5″ thick

Pleated filters are the most common of HVAC system filters and most systems rely on these filters alone. These filters are available in standard capacity or high capacity for longer life and dust holding capacity. Some systems may require the heavy duty version due to high velocity issues that cause the filters to pull through. Standard pleated filters are available in MERV 8 to MERV 13 and then mini pleats take over to MERV 15. Other options include carbon for odors or plastic and metal frames for specific applications.


V Cells-Rigid Cells-Bag Filters-4″ to 12″ thickness-65% to 95% Efficiency

These filters are often used as second or third layer of filtration to further reduce particle count and remove finer particles including viruses, bacteria and allergens. In many applications static pressure can be reduced by choosing these filters correctly. Speak with one of our staff to see what options may be available to improve filtration while not affecting the efficiency loss of using incorrect or inefficient filters.


Box style with gasket or gel seal 99.97% and 99.99% to 99.999% Efficiency

HEPA filters are primarily used in medical or clean room applications. Any environment that needs kept sterile will benefit from these extremely effective filters. A HEPA filter will remove virus particles but the air handling system must be designed to handle the high static pressure these filters create.
