Philips ac4080/10 [20/84] Water vinegar 1 1 1 hour

Note

• Make sure that the pre-lter is completely dry.

If it is still wet, bacteria may multiply in it and

shorten the lifetime of the pre-lter.

3 Mix the white vinegar with an equal

amount of tap water in a container that is

large enough to soak the humidication

lter in.

Note

• White vinegar has 5% acetic acid.

• If there are white deposits (limescale) on the

lter, make sure that the side with the white

deposits is immersed in the water.

4 Let the humidication lter soak in the

solution for one hour.

5 Discard the water-vinegar solution.

6 Rinse the humidication lter under the

tap to rinse away vinegar residues. During

rinsing, turn the humidication lter so that

both the front and back sides are rinsed.

7 Let excess water drip off the

humidication lter and let it air dry.

8 After the pre-lter and humidication lter

are put back in the appliance, reset the

lter lifetime counter. (Refer to chapter 7

"Resetting the lter lifetime counter")
