On the side that faces out is a non-woven pre-filter layer that helps to capture large particles like lint, hair, and fibers. It is glued in place with an airtight seal and is not removable from the filter assembly. At the top and bottom of the filter are pull tabs to help you remove it from the machine easily without disturbing the collected dust and debris. The frame of the filter is made from a durable plastic and all around the perimeter is a foam cushion that creates a soft but airtight seal to the machine’s housing. On the side that faces into the machine is the accordion fold HEPA filter that captures down to 0.1 micron particles, and there’s an activated carbon filter in between them to scrub out odors and organic VOCs. This filter is designed specifically for the Shark Air Purifier 4 which have model numbers that begin with HE4; mine is the HE401. Access for the filter compartment is at the back of the machine, and the cover panel is removed by simply pressing down on the two tabs as the top, tilting the top down and lifting it out. As you can see the original filter that I’ve had installed for over a year is completely covered in a thick layer of gray, trapped dust. That not only goes to show you how effective the machine is, but also how badly it’s needed in our home. The difference between the old and new filter is stark and I’m glad all this stuff was picked up by the air filter rather than us breathing it in. You’ll want to carefully pull on the top and bottom tabs to remove the old filter. Once removed, it’s a good idea to wipe down in the interior of the compartment with a dry cloth to collect any dust residue. Then to install the new filter, set the bottom edge of into the inner recess of the compartment first, then gently press the top and sides in. It should fit snugly and feel secure. Before we replace the back grill, let’s wipe down the interior as well for good measure. Then slot the two catches at the bottom into the holes at the bottom before snapping the top tabs in. On the machine, you can see how contaminated the air is since the new filter allows the sensors to detect particles better than the old clogged filter. To reset the filter life counter touch and hold the Filter Life message until the machine beeps 3 times. Now, we can set the operation mode to auto and let it do its thing and remove all the stuff in the air that could be causing you breathing and allergy problems. Overall, this aftermarket filter was a perfect fit, low-cost alternative to Shark’s OEM filters that works just as well.
