Wash your HEPA filter with warm water and allow it to dry if your model specifically states that water cleaning is safe. You can also soak your filter in hot water if it is extremely dirty. Clean non-washable, permanent HEPA filters using a vacuum to remove dust and debris.
You will never be able to vacuum all the stuff out. There's a ton of tiny particulates embedded in the filter that will make it harder to pull air through. Also reusing runs the risk of tearing the filter and then it's useless.
If your central air filter shows no signs of grime buildup, you can use the hose attachment from your vacuum cleaner or use a handheld vacuum to remove any debris.
Turn off and unplug the unit before starting any maintenance. Remove the front panel to access the filter. Either vacuum the filter while it's still in the unit or remove the filter from the unit. Use a vacuum cleaner to remove dust and debris from the pre-filter, which helps to extend the life of the main filter.
For non-washable, permanent HEPA filters, use a vacuum cleaner with a brush attachment to remove dust and debris. Never wash these filters with water, as it can cause damage.
You can rinse the filter in water, tap excess dust off of it or remove some dust with a vacuum, but this can definitely damage the mesh of fibers that allows the filter to remove particles from the air. Even if the filter looks undamaged, some of the fibers will be broken or stretched out.
Pre-filters should be gently vacuumed every 1–3 months. Many air purifiers have a pre-filter that captures larger particles like hair and dander before they reach the main filter, protecting your main or carbon filter so it doesn't clog up as quickly. Change pre-filters frequently, about every 1–3 months.
You can also soak your filter in hot water if it is extremely dirty. Clean non-washable, permanent HEPA filters using a vacuum to remove dust and debris. These types of filters are not designed to come into contact with water. Cleaning these permanent HEPA filters with water can cause damage.

The one exception to replacing a HEPA filter when it's dirty is if you have an air system that has a pre-filter in front of the HEPA filter, Negron says.
Although freshly vacuumed filters can look clean, they're still rife with debris, and they will negatively impact your IAQ and airflow within your HVAC system.
When the filter gets clogged, the air purifier must work harder, putting more strain on the components of the machine. Over time, this added wear and tear can lead to damage, and you may need to pay for repairs or replace your purifier.
Cleaning the air filter only improves its appearance. When should an air filter be replaced? The air filter should be replaced after the period indicated by the vehicle manufacturer.
It's generally recommended to change them along these timelines: True HEPA: 8,760 usable hours or about every 12 months. Activated Carbon: 8,760 usable hours or about every 12 months. Mesh Pre-Filter: Should be cleaned every 2-4 weeks.
Can You Have Too Many Air Purifiers? So, how about it? Can you have too many air purifiers in your home? If you have more air purifiers than is necessary, you do stand the chance of over-purifying the air in your home and using more energy than necessary.
HEPA filters can be vacuumed, but in the process, the HEPA filters are designed to trap particles up to 99% accuracy; this means that it's near impossible to vacuum all of the remaining particles and bacteria from the filter. You may end up damaging the filter by washing it, as it is extremely fragile.
A HEPA filter is a HEPA filter – it should work regardless of which type of vacuum cleaner it's in. So there's no reason a stick vac can't have just as good HEPA filtration as a corded barrel or upright vacuum cleaner.
Pre-Motor Foam & Felt Filters: Under normal usage, rinse clean every 3 months. Post-Motor HEPA Filter: Under normal usage, rinse clean every year or as needed. Rinse filters with water ONLY. Let all filters air-dry completely for at least 24 hours before reinstalling.
If there is a lot of dust, pet dander, or other particles inside your home, your air filter can get dirty very quickly. Construction, renovations, or a lot of pollution outside can also cause your filter to clog quickly.

This will help keep the air clean all day. As mentioned above, you may run the machine all night without any worries.
Although not all Shark upright vacuums have HEPA filters, we've found that the vast majority do, so if you have an upright model, it's quite likely that it has a HEPA filter. The Shark Rotator Lift-Away DuoClean PowerFins Upright Vacuum is one popular model that features a HEPA filter.
However, in general, the duration of use required depends on the size of your space and the amount of indoor pollution (which varies throughout the year). This is why most manufacturers will recommend you to leave your air purifier running all day, especially if it comes equipped with an automatic setting.
Room air cleaners are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. A standard room air cleaner, operating continuously, uses approximately 450 kWh per year in electricity. This is more than the energy used by some new refrigerators!
Mold is an obvious health risk in any home, but investing in an air purifier can help limit your exposure. The best among them will ideally offer HEPA-level filtration, with this level of filtration being able to trap up to 99.97% of airborne particles down to 0.3 microns in diameter.
