A cpap filter might seem to be a very small accessory of the machine, but is one of the most powerful and crucial parts of your medical device.
Changing or cleaning filters on your medical device is extremely important as it helps to keep your air supply clean and free of any contamination.
What Is A Cpap Filter?
A cpap filter is a motor-powered part of the machine that filters the air and ensures that people inhale clean air through their continuous positive airway pressure.
The air propelled from the machine passes through the filter and leaves back any kind of contamination inside the filter, giving you a clean supply of air to breathe.
Hence, a filter becomes one of the most important functions of a machine; most of these devices are required to be changed in every 1 to 2 months.
Different Types of Filters
The different types of filter available in the market depend largely on the cpap that you own from a particular manufacturer. The type of filters available today are.
Reusable: reusable filters, as the name suggests, can be periodically removed from your machine, cleaned and dried before being placed back into the machine. These filters are generally made with materials that can resist any type of washing and can be reused, although eventually they need a replacement.
Disposable: disposable filters need to be replaced every time you feel there is too much dirt on it; it is discolored or is broken. When you take out your disposable filter you should make sure that you immediately replace it with a new one, else you might have to take in contaminated air, which again will be extremely dangerous for your health.
If you have pets at home you may find that you need to replace the filter quite often than patients who do not have pets around their home environment. Replacing your filter every month is one of the best recommended frequencies for cpap filter replacement.
How Does A Filter Work?
A filter has been installed in a machine to remove any kind of allergens, bacteria or pollen from the air supply that you inhale from the machine. The filter ensures that all kinds of such bacteria are removed from the machine which otherwise could cause human infection in larger volumes.
The filter on the other hand also helps a patient to breathe easier, as any obstructions caused through dust can be removed with the help of a filter.
How Can I Replace My Cpap Filter?
Cpap requires very little maintenance and needs to be changed at least once in every month. Since filters keep away dust and allergens from the air supply that you inhale from the machine, you can be sure to find a lot of accumulated dust on the filter every time you open it for inspection. Here are some guidelines on how you can replace your filters:
Step one: every machine is built in a different way, but most machines have their filter at the back, near the power cord. If you have a foam filter you need to pinch it in the middle and drag slowly out of the machine.
Step two: Foam filters do not need anything that hold them in place, so all you need to do is to slide in the new filter into its opening. The slight friction created on the sides of the filter will help it to stay in place.
Step three: slowly remove the plastic cover which can be found at the bend of the air input into the cpap mask. Once the new filter has been placed, you can place this plastic cover back over the opening.
Possible Signs for Filter Replacement:
Although, it might not be possible to open up your cpap machine every now and then to inspect your filter, sometimes there are few signs that give you a clue that your machine needs a filter replacement.
- Decreased Airflow: one of the most common signs that you can notice when a filter needs a replacement is the decreased airflow from the cpap. The decrease in airflow is the result of any dirt clogging into the filter and is causing an obstruction for the air to flow easily into your mask.
- Infection: if you develop an allergy or infection while using a machine it may be because there are some bacterial developments in your filter. An immediate inspection in this case needs to be made to make sure that your infection does not get worse.
- Dust Particles: sometimes you might notice that the filter is not capable of holding back dust particles, but you might find these particles coming up right till your mask. This can be quite dangerous for patients to inhale, as they might develop infections.
Some manufacturers give additional filters along with their cpap headgear. Proper care should be taken while using these filters since low air pressure can make the cpap therapy extremely ineffective.
As a recommended rule, it is best if people try and stick to authorized filters with their cpap machines if they are not sure about the filter that might suit them best.
