Panel and Pleated Filters for Commercial HVAC
Commercial air handlers go through a lot of panel and pleated filters. We make pleated HVAC filters in MERV 8, 11 and 13, flat pre-filters in cardboard or metal frames, washable mesh panels, and carbon panels where odor control is needed.
Sizes run from 20×25×1 up to 595×595 mm in 1, 2 and 4 inch depths, or we cut to the dimensions on the order. Private-label packaging is also available.

FAQs
MERV 8 vs MERV 11 vs MERV 13 — which pleated filter do I need?
MERV 8 (≈G4) is the standard pre-filtration grade for AHU and rooftop intakes. MERV 11 (≈M6) adds finer particle capture for occupied commercial spaces, and MERV 13 (≈F7) captures fine particles for indoor-air-quality programs and for protecting downstream HEPA stages. All three run in the same face sizes and depths, so upgrading is usually a straight swap — send us your operating conditions and we'll recommend the grade.
Panel filter vs pleated filter — what's the difference?
A flat panel filter is the economical choice for coarse dust at low resistance. Pleating the media multiplies the filtration surface inside the same frame, which raises dust holding capacity and extends service life — that is why pleated filters dominate commercial HVAC. Washable metal and nylon mesh panels cover positions where filters are rinsed and reused instead of replaced.
How often should pleated HVAC filters be replaced?
Watch the pressure drop across the filter rather than the calendar — replacement is due when resistance reaches the system's rated final value. Loading varies with environment and runtime, so for steady consumption we help you set a rotation; most distributors and facility teams move to a monthly supply program.
Do you make washable panel filters?
Yes — washable metal mesh filters, nylon mesh filters and washable pleated pre-filters, with frames in aluminum, galvanized or stainless steel. They suit coarse-dust positions where rinse-and-reuse beats disposable replacement.
What is your MOQ and lead time for wholesale orders?
MOQ from 200 pieces. Free samples ship in 3 days; standard orders in 7–10 working days; bulk or custom orders in 15–20 days, with a green channel for urgent replacements.
Can you manufacture custom sizes or private-label filters?
Both. We build standard US and metric sizes — 20×25×1 through 5-inch depths, 595×595 metric — plus made-to-measure dimensions, and ship under your brand with private-label packaging and logo printing. Send your size list for a like-for-like quote.
