We do not hold a Phoenix parts list for the 1200 Desiccant, so the fitment above rests on CCW's own record rather than on a manufacturer document. It is a long-standing record and we have no reason to doubt it, but we are telling you what it is based on.
If you are ordering for a machine you have not filtered before, measure the old filter. Desiccant machines from the same maker use several filter sizes.
Why filters matter more on a desiccant machine
The desiccant wheel is the expensive component in these machines, and the filter is what protects it. Fine particulate that reaches the wheel blinds the media, and a blinded wheel is not a service item — it is a rotor and seal replacement.
A loaded filter also costs airflow directly, and on a desiccant machine reduced process airflow reduces grain depression capacity. The machine keeps running, appears to be working, and quietly takes longer to dry the structure.
Other filters on the same machine
Desiccant dehumidifiers run two air streams, each with its own filter — process air, which is dried and returned to the structure, and reactivation air, which is heated to drive moisture off the wheel and then exhausted.
On the Phoenix D850, for example, those are 4022636 (process) and 4027168 (reactivation). If your 1200 Desiccant has a second filter position, it needs servicing too. Ask us and we will check what the machine takes rather than have you replace one and forget the other.
When to change it
Between jobs on dusty work — fire, soot, demolition, disturbed insulation. Longer on clean water losses in occupied homes.
Do not wash a pleated media filter. Replace it.
Frequently asked questions
Can I wash and re-use it?
No.
Is this the only filter on the machine?
Desiccant machines normally have two. Ask us and we will confirm what your machine takes.
What does MERV 8 mean?
It is the media efficiency rating — the standard specification for this position.
Will it fit a D850?
No. The D850 process filter is 20" × 20" × 2" (4022636).
Tell us which desiccant machine you run and we will confirm every filter it takes so you can stock them properly.
