What MERV 10 Means in Practice
MERV is the efficiency rating of the filter media. A MERV 10 filter does real particulate work: well beyond a coarse dust screen, it holds the fine material a drying job generates.
The trade-off is that an efficient filter loads faster than a coarse one, and a loaded filter costs airflow. On a refrigerant dehumidifier, lost airflow across the coil costs water removal directly. The machine keeps running and quietly takes longer to dry the structure. Filter changes on a dehumidifier are performance maintenance, not housekeeping.
When to Change It
Change it between jobs on anything dusty: fire and soot work, demolition, sanding, or any site with disturbed insulation. On clean water losses in occupied homes it will last considerably longer.
Do not judge a pleated filter by its face. Look at it against the light and check the downstream side. A filter that has been through a soot job is finished regardless of how the front looks. Do not wash a pleated MERV filter; the media does not recover.

Frequently Asked Questions
Is this one filter or a case?
One filter. Order the quantity you need; keeping a few on the van means filters actually get changed.
Can I wash and re-use it?
No. It is a disposable pleated media filter.
Will it fit an R150 or 250MAX?
No. Those machines use different filters (4026315 on the R150, 4021475 on the 250MAX). Check your machine.
Can I run the machine without a filter?
No. You will load the evaporator coil with debris, and cleaning a coil costs far more than filters.
Tell us which Phoenix machines you run and we will make sure you are ordering the right filter for each of them.
