Dust Collector HEPA Cartridge Filter Upgrade Kit

Upgrade your single-stage dust collector with a retrofit filter that can capture even the finest of dusts. Independently certified HEPA media rated 99.97% efficient at 0.3 microns. Fits collector barrels that are 14"-20.25" O.D. in size.

Ditch the Bag and Get the HEPA Solution!

Standard cloth bag filters are a huge pain for woodworkers as fine dust can quickly clog the machine, causing suction loss and blowing the finest dusts (which are the most hazardous to your health) back into the air. That's why Oneida Air offers a convenient dust collector retrofit for both hobbyist and commercial shop owners alike. Simple to install, this kit will help you keep your shop (and your lungs) clean, healthy, and productive!

Unlike spunbond or nanofiber models, this HEPA cartridge filter requires no "seasoning" or filter-cake to reach peak filtration efficiency. It captures 99.97% of particles as small as 0.3 microns right out-of-the-box and immediately after cleanings. Learn More

Frequently Asked Questions
How do I clean this filter?

Clean this filter using compressed air blown from the outside of the filter. The nozzle should be angled roughly 20° and pointed into the filter's pleating. Keep the air nozzle at least 6" away from the filter to prevent damage to the filter media. We do not recommend using water to clean this filter.This cartridge filter has a pleating arrangement that is widely spaced for significantly faster and easier cleanings compared to competitive models. Additionally, the filter media is coated with a non-stick PTFE membrane that allows for quick dust release when cleaning.

How often should I clean the filter?

This can vary widely depending on how often your dust collector is used, and what kind of dusts it's exposed to. You should typically clean it only once you've noticed a considerable drop in suction performance. In our experience this can be around 1x per year, but with heavy amounts of sanding it could be as often as 1x per month. A pressure meter such as our Filter Efficiency Gauge can also be used to monitor pressure buildup.

When should I replace this filter?

With regular maintenance, our cartridge filters can easily last up to 5 years. Your filter should only be replaced if thorough cleanings do not help to restore your suction performance.

Which dust collectors does this filter work with?

The outside diameter of your collector's barrel must measure between 14" to 20-1/4" for the filter bracket to fit onto. A base plate adapter is included with this kit to create a flat surface for the filter to mount onto if necessary.The barrel's inside orifice (which is usually smaller in diameter to prevent dust from below swirling upwards) cannot be bigger than 13" in diameter. Refer to the product's Owner's Manual for more information.

Why should I upgrade my single-stage filter?

Standard single-stage dust collectors are typically equipped with a cloth bag filter rated for particles 1 micron in size. While effective for trapping some dusts, they still let through the smallest particles that are in fact the most damaging to your health as they can become deeply lodged within your sinus cavities. Additionally, many wood dust have been shown in studies to be carcinogenic. This independently certified HEPA filter captures 99.97% of particles as small as 0.3 microns (the same level of filtration used in hospital environments) so woodworkers can rest assured that their hobby won't hurt their health.

Will this retrofit filter affect my airflow?

Yes, it will improve it! This product has a significantly higher filtration surface area compared to cloth bags, which allows a higher volume of air to pass through and reducing pressure buildup.
