How to choose
Picking the best quiet air purifier with washable filter
Start with the two numbers that define this search: the rated noise level in sleep mode and the washable pre-filter. The Dr.Prepare lists 15 dB, the HEARBOBO lists 20 dB, the TER Air lists 22 dB and the Evalit lists 24 dB. Every pick here has a washable pre-filter, so compare the noise figure and the coverage the maker rates against your room.
Read coverage as the maker's figure
Coverage figures here are the makers' own ratings: 3,000 sq ft for the HEARBOBO, 2,500 sq ft for the TER Air, 2,200 sq ft for the Evalit and 1,075 sq ft for the Dr.Prepare. Match the figure to your room's floor area rather than treating it as a measured result. The HEARBOBO also states it can refresh up to 375 sq ft in about 8 minutes.
Washable pre-filter upkeep
A washable pre-filter catches large particles like pet hair and lint before they reach the main filter, which helps the main filter last longer. The HEARBOBO pre-filter can be vacuumed or rinsed and must dry completely before reinstalling, and the Dr.Prepare maker advises cleaning its pre-filter every 2 to 4 weeks. The TER Air and HEARBOBO replace the main filter every 3 to 6 months.
