In general, a HEPA filter needs to be changed every year, pre-filters last 30 days, and carbon filters can last three to six months. Clean permanent filters every three months and replace them if they are damaged. On average, most HEPA filters will last 6 to 12 months before they need to be replaced. However, heavy use and the amount of contaminants removed by the filter can affect its longevity.If a HEPA filter is left unused, it can remain viable for many years to come.
As an expert in air purification, I recommend changing the HEPA every 150 days approximately 8 hours a day or approximately every 1000 hours. You can adjust the number based on the number of hours you use it per day. Of course, mesh prefilters are a different story.The good news with these filters is that you can use them again and again without having to buy replacements. The bad news is that you usually have to clean them once every 2-4 weeks.
The other good news is that cleaning these filters is as easy as taking them out and cleaning them with a vacuum or a little warm water. If you wash them with warm water, allow them to dry completely on their own before putting them back in place and powering the unit.If you use a vacuum with a HEPA filter in a commercial environment, the filter needs to be changed much more often than once every two to three years. That's why all Hunter air purifiers have a filter replacement indicator built into the control panel to let you know if the filters are dirty. There are air purifiers that will need more frequent filter changes, so be sure to read your air cleaner's manual carefully to determine the life of the filter.
As an added benefit, the filters include an antibacterial treatment to prevent the growth of fungi, mold and odors.If you are using a vacuum with a HEPA filter in a strictly residential environment, the filter should last between two and three years before you need to replace it. So, if you're investing in a quality air purifier to improve indoor air quality, it pays to know the difference between HEPA and True HEPA filters. Depending on the size and type of air purifier you have, manufacturers have different suggestions for when to replace the HEPA filter. After your 12-month filtration cycle ends and it's time to swap out that true dust-filled HEPA for a new interceptive cleaning power panel, all you need to do is consult the owner's manual inside your respective purifier.However, improper installation or filtering of a larger, heavily contaminated space can shorten the average lifespan.
Many modern air purifiers come with filter change indicators, either in the form of a soft lighting reminder or an alert beep. For older models or those without gauges, it's helpful to keep a filter maintenance and replacement schedule on or around the unit, so you're always aware of when filters need to be changed. Most, if not all, cleaning professionals will tell you that the most efficient type of filter a vacuum can have is a high-efficiency particulate air filter or a HEPA filter.However, like HEPA filters, these filters will reach their maximum capacity and will no longer be able to remove any more gases from the air in your home. In addition, in addition to using an air purifier with a quality HEPA filter, reduce humidity and humidity in the air with a dehumidifier to improve air quality.
A HEPA filter, for example, uses thin layers of a porous material to capture small particles in the air.
