How They Work?

WoolGuard Filters work by using 100% wool, which captures grease while still allowing air to continue to pass through the hood system.

Once the wool filters are filled with enough grease, the kitchen employees can simply replace the filters.

Here is a video comparing a traditional kitchen hood system with a WoolGuard Hood Filter System:

Traditional baffle filters let around 82% of grease enter the hood system. Depending on your level of cooking, grease will accumulate and you’ll need to pay for frequent hood cleaning services. 

Hood cleanings cost at a minimum $400! 

However, there is a way to reduce your amount of hood cleanings by around 75%. Changing out your current baffle filters with WoolGuard Hood Filters will capture 98% of grease, only letting in around 2% of grease, which greatly reduces the amount of hood cleanings. 

When the wool captures enough grease and reaches the end of its life cycle, you simply replace them. 

Here is a diagram showing you what a WoolGuard Filter looks like brand new…and then when it needs replaced:

How Do I Get Started?

There’s a number of steps that need to happen before getting started. However, we’re excited to educate you and help you along the way. Here is the five step process to a cleaner hood system.

Step 1 - Facility Assessment

The first step is to determine if WoolGuard Hood Filters is worth installing. The answers to these questions will help us determine if installing WoolGuard Hood Filters is your best option in managing grease.

Step 2 - Schedule a Hood Cleaning

In order to keep your kitchen clean, we need to start clean. We require every new WoolGuard client to schedule a hood cleaning.

Step 3 - Purchase New Frames

Traditional baffle filters are not designed to hold WoolGuard Filters. To securely hold the WoolGuard Filter in place, we’ve designed a frame that will hold the grease-filled wool and allow air to come through.

Step 4 - Develop Initial Change-Out Schedule

Once the new frames and new filters are in place, we can develop a change-out schedule based upon your grease consumption.

You will be asked the following questions:

  1. How many times are your hoods cleaned per year?
  2. What days/hours of the week are you cooking?
  3. What appliances are you cooking with?

Answers to these questions will help us determine a good baseline as to when you’ll need to change-out your filters.

Also in this step, you must review a one-page handout of instructions to assure you understand how to change-out your filters properly.

Step 5 - Develop Precise Change-Out Schedule

Through the first few weeks, we want to work with you to hear how the filters are working. 

We also want to know how accurate the initial change-out schedule is.

After taking in your continuous feedback, we can develop (and send you) a precise change-out schedule like the one below:

Once you’re on a schedule that works, all you have to do is replace the filters when the change-out schedule says to….and you’re all good to go!
