Keeping your Shark Navigator vacuum running at its best means maintaining its filters. If you notice a loss of suction or a strange smell, it’s probably time for a change. This guide will show you exactly how to replace filter in shark navigator models, ensuring your vacuum works like new again. It’s a simple process that anyone can do in just a few minutes with the right know-how.
First, you need to identify which Shark Navigator model you own. The most common are the Lift-Away, Professional, and Upright models. While the steps are similar, there can be small differences. You’ll also need to know which filters your model uses. Most Shark Navigators have two main filters: a foam filter and a felt HEPA filter. Some newer models might have a combined filter cartridge. Don’t worry, we’ll cover all the variations.
Always unplug your vacuum cleaner before starting any maintenance. This is the most important safety step. You’ll be working inside the dust cup area, and we want to avoid any accidents. Make sure you have your replacement filters ready. You can find the correct model number on a sticker on the vacuum itself, usually on the back or bottom. Use this number to order genuine Shark filters or high-quality compatibles.
How to Replace Filter in Shark Navigator
This main section covers the universal steps for the classic two-filter system. Follow these instructions carefully for the best results.
Step 1: Access the Dust Cup
Locate the dust cup release button or latch on your vacuum’s body. It’s often near the handle. Press the button and lift the dust cup straight up and away from the vacuum base. You may need to empty the cup contents into a trash bin first. Give it a good tap to clear any fine dust.
Step 2: Remove the Old Filters
Inside the top of the dust cup compartment, you’ll see the filter housing. Twist the filter cover counter-clockwise to unlock it. Lift the cover off. Now, you can see the filters. First, remove the flat, rectangular felt HEPA filter. Then, take out the softer foam filter that sits beneath or around it. Be gentle to avoid tearing the old filters if they’re fragile.
Step 3: Clean the Filter Chamber
Before inserting new filters, take a moment to clean the empty filter chamber. Use a dry cloth or a soft brush to wipe away any loose dust, hair, or debris. This prevents clogging and helps the new filters last longer. Make sure the area is completely dry before proceeding.
Step 4: Install the New Foam Filter
Take your new foam filter. If it feels stiff, gently flex it a few times. Place it into the filter chamber first. It should sit flat and cover the entire base of the chamber. Some models have a specific orientation, so check if one side seems to fit better. The foam acts as a pre-filter, catching larger particles.
Step 5: Install the New Felt HEPA Filter
Now, place the new rectangular felt HEPA filter on top of the foam filter. It should align neatly with the grooves or shape of the chamber. There’s usually no wrong side, but if one side has a fabric-like texture and the other is smoother, the textured side often faces outwards. Just ensure it’s seated evenly.
Step 6: Reattach the Cover and Dust Cup
Place the filter cover back on top of the filters. Twist it clockwise until it clicks or locks into place. Don’t force it. Finally, align the dust cup with the vacuum body and push it down until it clicks securely. You should hear a solid snap. Plug your vacuum back in, and you’re ready to go with restored suction power.
Replacing Filters in Shark Navigator Lift-Away Models
The Lift-Away series is very popular. The process is almost identical, but accessing the filters can be slightly different. On these models, you often lift the entire dust cup and canister away from the floor nozzle. The filter compartment is located at the top of this canister unit. Remember to detach the hose if it’s in the way. The twist-to-open filter cover is very common on these. Just be sure you’re holding the canister securely when you twist the lid off.
Replacing the Post-Motor Filter (If Applicable)
Some Shark Navigator models, especially older ones, have a third filter called a post-motor filter. This is a small, rectangular filter usually located near the vacuum’s exhaust area, often behind a panel on the back of the body. You might need a screwdriver to open the panel. Check your user manual to see if your model has one. Replacing it follows the same principle: open the compartment, take the old filter out, put the new one in. This filter protects the vacuum’s motor from fine dust and should be changed periodically too.
How Often Should You Replace Shark Navigator Filters?
There’s no one-size-fits-all answer, as it depends on how much you vacuum and your home environment. Here’s a general guideline:
* Foam Filter: Can often be rinsed, dried, and reused. Check it every month. Replace it if it’s torn or permanently discolored, about every 6-12 months.
* Felt HEPA Filter: This should not be washed. Tap it gently to remove dust between changes. Replace it every 9 to 12 months for normal use. With pets or allergies, consider changing it every 6 months.
* Post-Motor Filter: Replace this every 12-18 months, or as recommended in your manual.
A clear sign you need to change filters is reduced suction even after emptying the dust cup. A burnt smell during use is another urgent warning sign.
Tips for Maintaining Your Filters
Proper care extends the life of your filters and keeps your vacuum performing well.
* Empty the Dust Cup Frequently: Don’t let it get completely full. Empty it after every few uses to reduce strain on the filters.
* Clean the Foam Filter Regularly: Rinse it under lukewarm water until the water runs clear. Squeeze out excess water (don’t wring) and let it air dry for a full 24 hours before reinstalling.
* Tap Out the HEPA Filter: Each time you empty the dust cup, gently tap the HEPA filter against the inside of a trash bin to dislodge surface dust.
* Check for Blockages: Sometimes, loss of suction is caused by a clog in the hose, wand, or brushroll, not the filter. Inspect these areas if you’ve already changed the filters.
Finding the Right Replacement Filters
Using the correct filters is crucial. The easiest way is to use the model number from your vacuum’s sticker. You can buy genuine Shark replacement parts from their website or authorized retailers. Many third-party companies also make high-quality, compatible filters that are more affordable. Read reviews to ensure they have good sealing and filtration quality. Avoid the cheapest, no-name filters as they may let dust through or damage your vacuum.
Troubleshooting Common Problems After Replacement
What if you replace the filters and your vacuum still has problems? Here’s what to check:
* No Suction: Did you remember to reinstall the foam filter? Leaving it out causes a massive air leak. Also, ensure the filter cover is twisted on completely and the dust cup is locked in.
* Weird Noise or Whistling: This usually indicates an air leak. Check that all filters are seated properly and that the cover is sealed tight. A torn foam filter can also cause this.
* Vacuum Overheating or Smelling: Did you install a damp foam filter? It must be bone dry. Also, verify you didn’t accidentally block the airpath by misaligning a filter.
Taking care of your Shark Navigator is straightforward when you know the steps. Regular filter replacement is the single most effective thing you can do to maintain its power and longevity. It’s a small task that makes a huge difference in your cleaning results.
Frequently Asked Questions (FAQ)
Can you wash Shark Navigator HEPA filters?
No, you should not wash the felt HEPA filter. Washing will ruin its delicate fibers and its ability to trap microscopic particles. You can only gently tap it to remove loose dust. The foam pre-filter, however, is designed to be rinsed and air-dried.
Where is the filter on a Shark vacuum?
In most Shark Navigator vacuums, the main filters are located inside the top of the dust cup compartment. You need to remove the dust cup, then twist off the filter cover to access them. A secondary post-motor filter might be on the back of the vacuum’s body.
How do I know if my Shark vacuum filter is clogged?
The most obvious sign is a significant loss of suction power, even after you’ve emptied the dust cup. The vacuum may also sound strained or louder than usual. If the filters look caked with dust and are discolored, it’s definitely time for a change or a clean (for the foam filter).
Why does my Shark Navigator smell bad when I use it?
A burning or dusty smell often points to a dirty or clogged filter. The motor is working harder to pull air through. First, replace the HEPA filter and clean the foam filter. If the smell persists, check for blockages in the hose or brushroll, as trapped debris can overheat.
Are generic Shark filters any good?
Many generic or compatible filters are very good and offer a cost-effective alternative. Look for brands with positive customer feedback that specifically list your Shark model number as compatible. Avoid extremely cheap filters, as they may not seal properly, allowing dust to bypass and potentially harm the motor. Genuine Shark filters guarantee a perfect fit and filtration spec.
How long do Shark vacuum filters typically last?
With average use, a foam filter can last 6-12 months with regular cleaning. A felt HEPA filter should be replaced every 9-12 months. If you have pets, allergies, or a very dusty home, you may need to change them more frequently, perhaps every 6 months. Always go by performance—if suction drops, check the filters first.
Remember, maintaining your vacuum is a simple but essential chore. By following this guide on how to replace filter in shark navigator models, you’ll keep your machine running effectively for years to come, ensuring your home stays clean with minimal effort. Just take your time, follow the steps, and you’ll be done before you know it.
