These ultra fine filters are an alternative to the black coarse filters for the Apex XT range, Zzz-PAP machines and PureSom CPAP systems. Please note these are not made by the original manufacturers but by CareFusion. These air filters are of a similar quality to the original filters. They come in a pack of two.

Why buy alternative filters?

Our filters are often cheaper than the branded originals even though they are of similar quality. Unlike the CPAP machine, there is nothing high-tech about foam and paper filters so there is nothing to worry about in terms of compromising on air quality and so on. It could also be that you are placing an order for another item here anyway so you might as well get some filters at the same time, avoiding packaging and postage costs.

How often should I replace filters?

This depends on the air quality in your bedroom and how prone you are to allergic reactions. If you live near an industrial area or busy road you may have to replace them every month. If your property suffers from damp and mould you are also more likely to need replacement CPAP filters more often. Inspect the filter every week and make sure you have some spares ready. Apex recommend changing this particular filter every six months.
