In a nutshell, yes you can but partially but how, let’s find out.

1.   Cleaning of Holmes Air Purifier Pre Filter?

Most Holmes units use a washable foam pre-filter. You can simply wash these filters under running water, sink, or in the tub with your regular soap and luke water.

Note: Make it a habit of checking the filter every 14-20 days check the conditions of your Holmes’s pre-filter for better performance.

Here are some steps to wash and check the filter

  1. Turn off and unplug the unit
  2. Open the front inlet and remove the pre-filter frame
  3. Examine the pre-filter and notice if there is any dust and dander accumulation. If so, you wash it in warm soapy water gently and rinse it gently with your hands with soapy water. Or you can use a soft cloth too for this particular action.

When should I change Holmes Air Purifier Pre-filter?

 Pre-filters are usually made to run longer than other filters as they only have to capture large particles like fiber, dirt and pet hair, etc.  There is no need to change your pre-filter as you can wash it with water after every 15 days. However, it can be changed only if it gets damaged or torn.

2.   Cleaning the HEPA filter of Holmes Air Purifier

Holmes Purifier has a HEPA filter too that needs to be replaced every 6 to 8 months. As it is a permanent filter, you need to check the condition first and remove it in case of dirt. The modern air purifier comes with the indicators that will notify probably after every three months or when the performance is compromised.

Disposable HEPA filters consist of mainly two fibers; 80% polyester and cellulose blend. These two fibers are tightly weaved into a webby structure that has ultra-small holes to trap VOCs and other particles and finally an Expanded Polytetrafluoroethylene coating is laid on the filter that is called efficiency-enhancing coating. That is why we never recommend washing your Holmes HEPA filter.

While you are washing your Holmes HEPA filter, try not to take it directly under running water because the pressure will widen the pores of the weaved fiber, and weakens the structure of the HEPA filter.

For cleaning your Permanent HEPA filter, you can use a blower or vacuum (at low speed). The burst of compressed air up to 50 PSI will remove all the dirt particles easily.

Here are the step to clean the filter

  1. Turn off and unplug the air purifier
  2. Remove the air grill from the front side by pushing Tab
  3. Check the condition of the permanent filter and remove it if there is dirt. Remember, don’t wash it with water. Clean it with a vacuum cleaner.
  4. You can also run the brush on both sides of the filter. The filter may disappear its color but it will not affect its performance.

Don’t use water or even a damp cloth to clean the HEPA filter of Holmes.

When should you replace the HEPA filter?

HEPA filters are usually made for long-term use. In general, a HEPA filter can be used for 12 to 18 months depending upon the usage and the quality of air in your area. However, for some units, it is recommended to replace the air purifier within 6 to 8 months. The HEPA filter will cost you within the range of $ 20 – $ 95 depending upon the quality, size, coverage area, and manufacturer.

3.   Carbon Filters of Holmes Air Purifier

A carbon filter, also known as an Odor filter or charcoal filter plays a vital role to eliminate the particles left by the HEPA filter, usually gases and smoke. The perfect carbon filter can reduce wildfire smoke particles, irritating smells, and digger smoke.

Holmes air purifier carbon filter is not recommended to wash however, you can clean this filter using a vacuum similar to the HEPA filter.

Here are the steps to clean Carbon/odor filter

  2. Attach a crevice tool to your vacuum and move the vacuum on both sides of the filter from distance.

When should we replace the Carbon filter?

As the carbon filter is the last stage of filtration it captures every particle skipped by the other two filters. Halmos suggest replacing their carbon filter every 3-6 months depending on the usage and coverage.

Here is a tip, It is better to replace the carbon filter than to clean it by vacuum. Change the Carbon filter when it gets too dirty. An activated carbon filter can cost around $5 to $10 depending upon manufacturers and unit capacity.
