Optrel Swiss Air PAPR Pre-Filter – Pack of 50
Optrel Swiss Air PAPR Pre-Filter to protect the particle filter.
In combination with the master filter, this results in the highest filter class TH3 and thus filters 99.8% of all pollutants from the air.
No aerosols, smoke, particles or viruses can get through the pre-filter. It should always be fitted in front of the main filter. This ensures the larger particulates are removed first and drastically extends the life of the Swiss Air main filter.
Pack of 50.
