This is a very common question that we were asked. The air filtering system inside of the Shark Navigator Lift-Away NV360 has to be regularly cleaned for them to perform at their best. And if you have read our previous reviews, you will also know that if they’re cared for well enough, you may never need to replace them. However, if your filters are coming apart and you need to replace them, the process is simple and you can do it in only a few minutes. Find the Correct Filter Replacement Kit First, you need to find a compatible filter replacement kit online. They are (at the moment of writing) fairly easy to find and are also affordable to boot. Just search for the model number (Shark NV360) along with the search term “filter replacement kit” and you should have plenty of options to pick from. You have two options, here. You can either buy directly from Shark’s store. They are still selling filter replacement parts. Because you will be buying directly from the company, the quality is guaranteed. However, according to our data, several third-party manufacturers who offer NV360’s replacement filters have good quality track records, too. This kit, for example, is very well-rated among users. Whichever outlet you purchase from, the kit should contain three filter pieces: a foam filter, a felt filter, and a HEPA filter. The foam and felt filters make up the vacuum’s pre-motor filtration. Though they are not as efficient as the HEPA filter, they can do a good job at preventing large particles like dust and visible debris from being ingested by the motor. They also reduce the HEPA filter’s workload significantly by trapping large particles. Then, there’s the HEPA filter. It eliminates anything that has managed to slip through the pre-motor filters. With its high-efficiency filtering rate (99.97% of 0.3 microns particles), it will be able to do a good enough job to protect even users who suffer from allergies. How to Replace the Filters Replacing the Pre-Motor Filters The first thing you have to do is remove the dust cup from the vacuum. You can do this by locating and unhooking the two latches on either side of the cup. They anchor the dust cup to the rest of the vacuum. Once the latches are off, grab the cup using the top handle and lift it away from the vacuum. The compartment holding the foam filter will be revealed underneath the spot where the cup had once sat. With clean hands, grab the foam filter by the corner and lift it out. Directly beneath the foam filter will also be the felt filter. There will be a small lifting tab on the surface of the felt filter. You can extricate it from the vacuum by grabbing onto the tab and pull. When both the old filters have been removed, install the new filters by reversing the process. Place the dust cup back into place once you are done changing out the two pre-motor filters. Replacing the HEPA Filter The HEPA filter sits in a different compartment than the pre-motor filters, so the replacement process will be drastically different. Fortunately, taking out and changing the HEPA filter is much simpler. First, you have to locate the door to the HEPA filter compartment. Look at the front of the vacuum and find the silver air vent with the words “Lift-Away Deluxe” emblazoned across the middle. Behind that portion is the HEPA filter. Look for a small latch at the bottom of this vent. It should be centered relative to the door. If it is too difficult to find, you can refer to the user’s manual. When the latch is located, you have to pull outward to release it. Unhooking the latch and the cover door will come loose. Remove the door and you will find the HEPA filter behind it. In order to remove the HEPA filter, grab onto the small, protruding tab in the middle of the filter’s grate. If you pull and it doesn’t budge for the first time, don’t worry. The HEPA filter is notoriously difficult to remove, so give it some time and some vigorous wiggling. When the old filter finally comes loose, put the new filter in place, install the cover door, and you’re finished!
