Humidifiers are the best inventions for dry winter season. It helps to eliminate dry air in the atmosphere and thus reduces the chance of getting attacked by airborne diseases and various other ailments caused due to dry air.
However it should be noted that the device requires regular cleaning and maintenance after a periodic usage, so that you can enjoy maximum benefits out of it for long.
Mineral deposits, which are often seen within the device and on filters should be cleaned thoroughly once in a week so that your unit does not go wrong.
Below you can find some of the basic steps, tips and advice on how you can clean your humidifier filter without any mess or hassle.
How to Clean a Humidifier Filter?
Humidifier, only in good working condition, can help you enjoy most comfortable days and restful nights without any issue.
If you and your family rely on one of these humidifying devices, you should definitely adopt a habit to clean its removable filter on regular intervals.
No matter what brand of humidifier you use (Vicks, Honeywell, Bionaire, Homedics, Crane or any other), the very basic steps you need to follow for routine cleaning of your humidifier filter remains the same.
Step 1: Unplug your humidifier, remove the tank of the unit and drain off the old left over water to set aside the tank.
Step 2: Now remove the outer casing of the device and take out the reusable dirty filter (which is most of the times located inside the motor housing of your device).
Step 3: Now just by looking on your humidifier wick filter, you can judge about the level of cleaning it may require.
If the filters are slightly dusty, these can be cleaned easily by just soaking and rinsing in fresh cool tap water.
You can use your old unused toothbrush for lightly brushing away the debris that is stuck on the filter. Once you find your filter clean, rinse and shake off the water finally.
Step 4: Now when you have cleaned your filter, care that you do not leave it wet for long. Use an absorbent towel and place the wet filter on it.
Allow it dry naturally (in 1-2 hours) and do not use the tools like hair dryer as it can damage them permanently.
☑ Note: Although the routine cleaning of filters (as mentioned above) are good enough to keep your humidifier in healthy working condition, using vinegar or bleach is highly recommended if you are particularly concerned about growing humidifier filter mold.
Treating the humidifier filter with vinegar or bleach-based cleaning solutions is also useful if the filter is excessively contaminated and hard to clean.
How to Clean Humidifier Filter With Vinegar?
Vinegar is one of the best cleaning agent (due to its natural acidic properties) that can be used for cleaning very dirty filters.
Disinfecting or sanitizing your humidifier filter once in a week or two is always recommended.
You can do this by using liquid solutions like vinegar or bleach that offers better cleanliness and functioning for long – without you worrying about growing molds on your humidifier wick filters.
For cleaning humidifier filters with vinegar all you need is:
- Distilled White Vinegar
- Towels and Rubber gloves
- Bucket and Soft cloth for wiping clean
Step 1: Unplug the device, remove the tank and drain the water from the water tray.
Step 2: Set the water tank on a clean towel and remove the filter as per the instructions in the instruction manual.
Take care and remember the steps while dissembling the filter so that you can easily assemble it again after cleaning.
Step 3: Now fill warm water in the bucket (a large container or sink) and place the filter in it.
Make sure that it is completely soaked without any top layer floating on.
Step 4: Add distilled white vinegar in the water (in a ratio 1:2). Mix it gently using your hand. Use gloves if needed.
Step 5: As you are rinsing the filters, look for any damaged or decomposed areas.
You may have green molds, black or pink deposits and even mineral deposits at the corners or in the main areas.
Clean them if required by little scrubbing. You can use soft brush for this.
Step 6: Allow the filter to be soaked in the solution for an 40-60 minutes. The more it is immersed in solution, better the results that are achieved.
Step 7: Now check the filters for deposits or any dirt settled on it. Place it back in solution if required for some more time.
Step 8: Now remove the humidifier filter and rinse it thoroughly in clean and cool water, let it dry naturally for sometime.
Drying your filters is important before you place it back in the humidifier machine.
Step 9: Empty out the left vinegar solution and clean the water tray/tank with soapy hot water, repeat the method with clean water.
Step 10: Fill the tank and place the filters back in their position to let it function in a normal way.
This process of cleaning the filters in vinegar solution should be followed every week or month, based upon the usage and rate of deposits that builds up on filter.
Besides this, you can follow the manufacturer’s instructions and recommendation to accomplish safer cleaning.
How To Clean Whole House Humidifier Filter?
Cleaning the filters of your whole house humidifier (like an Aprilaire humidifier) can be bit tricky and time consuming, than as compared to portable ultrasonic humidifiers.
However following the guidelines given in your Humidifer’s Owner’s Manual can help you go through the process easily.
The basic steps that you need to follow while cleaning your furnace mounted humidifier and its filter are as follows:
- Switch off the power supply and unplug the device
- Now disassemble your humidifier device to access the inside of the unit
- Drain out the left over water in the reservoir and fill clean fresh water (to about 2/3rd level)
- Add small amount of chlorine bleach that will take care of microbes and viruses present in the tank.
- Now whirl around the water solution slowly to clean the reservoir tank so that it gets free from growing molds
- Check for the scale build-up at the corners and make sure that it also gets removed
- Now drain out the water solution and fill it again with fresh water. Rinse and clean the reservoir slowly.
Now that you have cleaned the unit and reservoir, you need to clean the filter (water panel, water pad or evaporator pad).
Before cleaning, check in your instruction manual – whether if your specific whole house humidifier model allows it to get cleaned.
If the filters are reusable and need cleaning, you can clean remove and clean them by immersing/soaking in clean cold water. Use vinegar if it’s too dirty.
If the wick filter or water panel in your furnace humidifier is not washable, you need to replace them annually.
Warning, Tips and Advice
Cleaning the filters, whether furnace humidifier or a portable room humidifier, is a task which should be done with proper care. Here are few important points you should care for:
=> Using formulated solutions (other than vinegar or bleach) for disinfecting the humidifier air filters can progressively worsen out the synthetic material of the filters and should be therefore avoided.
=> If you are using bleach instead of vinegar for sterilizing or cleaning extensive mold on filters, be ensured that you wear gloves and work in a ventilated area.
Add proper amount of water (more than you used while preparing vinegar solution) as it is bit hard.
=> Make a note that if your humidifier filters are too dirty to be cleaned, do not waste the time and energy for cleaning them.
These stubborn filters may seem to be clean after a regular cleaning, but may contain various viruses and bacteria left behind. These may be highly dangerous for your family, especially for babies.
As filters of most popular humidifier models are readily available online at a most affordable price, you can check and buy a new humidifier filter for your particular model, before trying to clean them.
I personally recommend that you should go for cleaning the moldy air filter ONLY if you find that it is not available in the market, for your machine type and model.
If available, throwing the old one and buying new is the best option.
Check online, buy and get it replaced in an easy way; just to ensure that your family enjoys the best hygienically clean mist of air all the time in all seasons.
