Guarantees longer product life for the main filter
If a room is especially dusty or if space is shared with pets then a timely change of the Allermed pre-filter is recommended. The particle filter protects the main filter cartridge material. In this way the air purifier produces clean air for longer. The pre-filter for particles, dust and animal hair is made of a special non-woven fabric and is placed around the main filter cartridge. Depending on the model of the large Allermed air purifier, the Permaflit particle pre-filter material can be cut to size.

How often should I change the pre-filter?
The frequency in which the Permaflit particle filter should be changed depends on the amount of dust and on the number of birds, cats, dogs and other furry creatures living in the house. People with allergies and asthma should change the pre-filter of the Allermed air purifier more frequently. A seasonal change is recommended to reduce allergy triggers such as dust mites and pollens. Largely it depends on the personal circumstances and on how often the air purifier is in use but generally it can be said that the pre-filter should be changed every 6 months.
Please note: Experts advise against washing the filter. The pre-filter can be disposed of in domestic waste bins.
