WoolGuard Filter system

Exhaust hoods are responsible for preventing grease and other debris from dirtying up the kitchen, as well as helping to prevent fires. In order for the exhaust hood to properly do its job you need to properly maintain it, and one of the most overlooked preventative measures is replacing the exhaust hood filters.

The tricky part about exhaust hood filters is that unlike your common AC filters, which you’re supposed to change every 30 days, there is no set schedule for when you should replace the hood filters. There are several factors that come into play in terms of the time frame between changing the filters.

Filter Construction:
What material is your filter made out? Stainless steel filters are known to outlast aluminum or galvanized filters, and a heavy duty filter will almost always outlast a standard filter.

Heat Exposure:
How much heat is the hood being exposed to? The more heat the unit is exposed to the more wear and tear on the filter which can cause it to break down sooner.

Maintenance:
If you are performing preventative maintenance regularly on your exhaust hood be sure to inspect the hood filter often. Look for signs of wear and damage which may prevent the filter from a tight fit in the opening, such as corrosion, dents, warping, and holes in the filter. If you notice damage, you should consider replacement. If you are cleaning your filter, be sure to avoid harsh cleaning chemicals, especially bleach, as it can lead to corrosion. Hand washing filters is the most efficient way to clean the filters which also helps prolong the filter life.

WoolGuard Hood Filters are stainless steel filters which require fewer cleanings thanks to the disposable wool inserts that help to capture up to 98% of airborne grease particles.
