Can You Wash A Honeywell Air Purifier Filter?

When wondering how to clean Honeywell air purifier permanent filters, customers often consider using soap and water to remove the dust. While this can be effective with certain washable filters, it could damage or hinder other kinds. The types of Honeywell filters available include:

  • Washable filters
  • Activated carbon filters
  • HEPA permanent filters

The latter two should only be brushed and vacuumed, or else they could damage the filter or the unit. If you are ever unsure, follow manual or product instructions for best practices. If you can wash it, make sure to check if soap can be used or if only water is enough.

How Often Should You Clean The Honeywell Air Purifier Filter?

Need to know how often to clean central air purifier filters? The best cleaning schedule for your filter will depend on a variety of factors, including the air quality in your area, how often you use your air purifier, what kind of filter you have installed, and more.

As a general guide, we would recommend washing washable filters once a month, while activated carbon and permanent HEPA filters are a little more flexible. We recommend once every 1-3 months or so for the latter two. Your filter light should be a good indicator, but set reminders in your calendar, so you never miss a cleaning date.

How To Tell That The Honeywell Air Purifier Filter Is Dirty?

Most Honeywell air purifiers have a filter light that tells you when it needs cleaning, replacing, or fixing. However, sometimes it may not work or could be compromised. Some other things to watch out for include:

  • It has been a while since it was last cleaned.
  • The air does not seem to be improving in quality even if you leave the purifier on for an extended time.
  • The purifier is particularly warm.
  • The air purifier makes odd noises while running.

If you are ever unsure if a filter needs cleaning, the fastest way to know is to take it out and inspect it for yourself.
