Range Hood Air Filters

Permatron range hood filters collect odors, dust and grease in your ductless range hood systems, chimney hoods or extractor hoods. Air filters can also be used in some microwave ovens and bath fans. UL Classified as to Flammability Only. Permatron’s 1/8″ – 1/2″ thick aluminum Model RH series air filters come in three styles for compatibility with nearly all hood systems:

  • Model RH. These framed aluminum hood filters contain multiple layers of bonded aluminum in 1/8″-1/4″ thickness or multiple layers of bonded and corrugated aluminum in 1/2″ thickness that will capture dust and grease. Rinse clean with water and a mild spray cleaner. These aluminum hood filters carry a 5 year warranty.
  • Model RHAC. These hood filters contain coconut shell activated charcoal carbon impregnated nonwoven polyester media with fire retardant supported by lightweight aluminum mesh. Made with nonwoven polyester, these dual action carbon filters capture dust and grease, while the activated carbon adsorbs odors and fumes. Replace this disposable air filter as needed.
  • Model CTF-RANGEHOOD is a 15″ X 19″ x 1/4″ cut-to-fit sheet of bonded aluminum mesh. Can be gently rinsed with water and a mile spray cleaner; replace as needed.


  • You really put the “Service” in Customer Service.  So many people would have just said no. I appreciate your taking that extra step by referring me to Reilly Foam. Permatron customers are lucky to have you in their corner. Thanks for all the help.

  • The distributor you got me in contact with sent me the three PreVent Model R filters I was looking for. They are working great. Thank You.

  • Everything was correct & professionally served, finely crafted with accurate dimensions of quality material. I will purchase further metal mesh filters from your firm in the future as demand calls for.

  • We had to change a combined condensing / free cooling coil because it was so badly damaged from debris and washing. 10k€ (approx. $12,000 USD)  for the coil and works and 6k€ (approx. $7000 USD) for the crane hire. The second chiller on the site is perfect as the screen was fitted back some time ago.

  • The filters we purchased are a great addition to our plant operations.  I am looking at other applications for their use…

  • The order process went very well.  We received the black washable fan bonnets 2 weeks ago and are very happy.  I will order again in the future.   Great product and great service.  Thank You!

  • It’s always a great idea to protect HVAC condenser coils with screening, especially if you can do it right after new equipment installation. Once the magnets where inserted into the screen grommets, it took literally less than a minute to place the screening on the equipment, adjust it, done. This screening will protect the condenser coils from grass cutting, bugs, cottonwood seedlings, etc.

  • Our customer, Logoplaste, uses and raves about the Prevent BHA Screens and MagnaMount Kits.We did an install at their manufacturing facility in June on two units, all four sides required screens. Installation time was drastically reduced from the original 6 hour estimate with standard mount clips, to complete screen installation in under 1 hour with MagnaMount clips.The facility is located along the river where cottonwood trees are very abundant. Even when installing PreVent, it was catching the cottonwood that was flying. I brought him out one of your cleaning brooms a week after install, and the Maintenance Manager said that it is the best money he has spent since he has worked at that facility. He is planning on purchasing some more for his 4 Cooling Towers as well.

  • The PreVent bonnet style filter is the best thing I have ever bought to protect our cooling tower circular fan. We have to clean it every two weeks but it is so easy.
