Features & Benefits


This is a replacement evaporative filter for the new style Air-O-Swiss Room Humidifier.

The filter is made from environmentally friendly paper with cotton flocking and guarantees high humidifying performance.

On average the filters need to be replaced every 2-3 months but in hard water areas such as London and the South Coast the filters could need to be changed every 1-2 months.

These filters should not be washed or wrung out.

You can dispose of old evaporative filters with the household waste.

For a longer service life we recommend the use of an Ionic Silver Stick to reduce the formation of bacteria.

Part no: AOS05910

What can I say? The humidifier won't work without this product and then my workshop would be far too dry for the harpsichords I make restore and repair.

Delivered quickly on the day stated and within the one-hour time slot notified by e-mail on the morning of delivery. The humidifier works better now the filter has been replaced.

Excellent product, but in hard water area like London, need to change at least every 2 months.

Same comments as for 2251 above.

This seems to work well but I find in London it has to be replaced more often than suggested as it clogs up with calcium from the hard local tap water (perhaps I should use softened water???) and dust from the city atmosphere. We live on a crossroads of 2 minor roads where the wind can whip round and deposit alot of fine dust from the roads as it does so.

Excellent product, but only last 6-8 weeks in London, which is a hard water area.

Having taken out the old filter and put in a new one, the humidifer seems to be working better.

The same comments apply as listed for the AOS 2251.

Excellent product. With me, only lasts 2 months, rather than £. (Hard water in London?) Delivery was very well executed, and time of delivery was exactly right.

I find it very effective. Only slight weakness with design is when we have to turn filter unit upside down and placing the motor housing on top of it: it can easily get squashed by the motor housing.
