Kröber Dust Filter, 5-Pack

The Kröber 4.0 is known as one of the quietest oxygen concentrators on the market (31 dB). To maintain this low noise level and high performance, it is essential that the dust filter be replaced monthly. A clogged filter increases resistance at the air intake, causing the device to work harder and potentially produce more noise. This 5-pack provides a 5-month supply and is more cost-effective per unit than purchasing individually. Each filter is easy to install yourself without tools

Key Features: 5 pieces per package — 5-month supply | Replace monthly | Maintain Kröber’s whisper-quiet noise level | Easy to install yourself | Brand: Kröber Medical

Practical tips
A dirty filter in the Kröber 4.0 can measurably increase the noise level. Regular replacement is the easiest way to keep the concentrator quiet.
