You cannot wash Dyson air purifier filters because this will damage them, but you can rinse or replace these filters.
High efficiency particulate air (HEPA) filters are known to be some of the most effective air filters on the market and can remove the majority of impurities from the air in your room or space.
Dyson air purifiers include HEPA air filters, and in some cases, carbon filters. These filters cannot be washed but can only be rinsed or replaced.
The pros and cons of HEPA filters
HEPA filters are a kind of pleated air filter that are known for being particularly effective at filtering out particulates from the air. HEPA filters can filter up to 99.97 percent of particles as small as 0.3 microns from the air.
This is good because it means that HEPA filters can filter circulated air and make sure that dust and dirt do not enter your lungs.
However, though these HEPA filters are so effective in filtering particulates in the air, they cannot filter gases, fumes, chemicals, and odours. HEPA filters can also be more expensive than other types of filters and can be quite fragile and delicate to handle.
Can you wash Dyson air purifier filters?
Dyson is known for creating especially stylish and effective air purifiers. For this reason, Dyson air purifiers like the Dyson TP01 Pure Cool include HEPA filters in their designs, to ensure that their purifiers are as effective at removing impurities from the air in your space as possible.
Models like the PH04 also have carbon filters inside the HEPA filters.
Regardless of whether your model only has HEPA or has HEPA and carbon filters, the best way to determine whether your filters need to be cleaned is to leave a clean, white sheet a few inches in front of the air purifier for an hour. If the sheet has changed colour after the hour is up, it is time to change your filters.
The problem with the sleek design of these Dyson air purifiers is that the HEPA filters are extremely delicate and, therefore, cannot be washed.
You will be able to open the various Dyson air purifier models, including ones with round and half-circle filters, and remove these filters, but you will only be able to rinse the filters and you cannot wash them with soap or detergent.
However, since the function of filters is to catch dirt and impurities in the circulating air, these particles will build up on the filter over time, even if you rinse your filters regularly.
This means that the best option when the filters get so dirty that simply rinsing does not clean them anymore, is to purchase replacement filters for your Dyson air purifier.
How to remove the filters from Dyson air purifiers before you rinse them
The process to remove the filters for every Dyson air purifier model will be slightly different, but you should always make sure that the unit is switched off before you start.
In the case of models like the Dyson TP07 Smart Air Purifier and Fan, which has a Pure Cool tower-like design, you need to push down the clips on either side of the bottom compartment of the model to remove the casing.
Then you can remove the half-circle HEPA filters by pushing the tops of the compartments and removing the carbon filters by slightly tugging at them.
For other models, such as the BP01 HEPA Air Purifier & Fan, you need to unscrew the top of your air purifier to be able to remove the circular filter from the centre of the unit.
How to rinse your Dyson air purifier filter
Once you have removed the half-circle or circular filters from your Dyson air purifier, you can begin to rinse the filter.
If you are feeling particularly daring, you can lightly tap the edges of the filter on a trash can to get rid of the majority of the dust and debris on it, but you should be careful not to damage the folds on the filter.
You can then rinse your HEPA under cold water and leave it to dry for at least 24 hours before placing it back in its position in the unit. Using any soap or detergents will damage your filter.
How to replace your Dyson air purifier filter
Dyson air purifier filters tend to get dirty, even with frequent rinsing, and need to be replaced every year.
Fortunately, this only requires that you purchase a replacement circular filter, like this Colorfullife Replacement Air Purifier Filter for $34.99 or this Insinlive half-circle filter pack for $51.11, which also includes the carbon filters that cannot be washed and can only be replaced.
