This can vary widely depending on how often your dust collector is used and what kind of dusts it's exposed to but you should typically clean it only once you've noticed a considerable drop in suction performance. In our experience this can be around once per year, but with heavy amounts of sanding it could be as often as once per month.
A meter such as our Filter Efficiency Gauge can also be used to monitor pressure buildup and inform you when the filter need's to be cleaned.
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.
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.
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.
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.
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.
The actual number doesn't really matter. It will be higher when you have more gates open, more airflow through the system and thus more back-pressure on the filter What we really care about is the change in the number. So, take a baseline reading (or set of readings) and monitor them. When the filter gets dirty the pressure and gauge reading will go up. When the reading changes say 1-2" on the gauge that's a good indicator of when you'd want to clean. None of this is exact science but rather an indication of pressure buildup in the filter. Also, cleaning it more often (when the buildup is lower) will normally be easier and quicker than waiting for the filter to be dirtier.
