The Record Power AC400 air cleaner needed a new set of filters having not been replaced since being purchased back in Sept 2012 (nearly 4 years ago!). To be fair I did actually vacuum the external filters from time to time. I bought the replacements from Yandle and Sons:-
- Record Power Replacement Outer Paper Filter for AC400 Air Cleaner (RPOSAC400-27) £9.99
- Record Power Replacement Inner Filter for AC400 Air Cleaner (RPOSAC400-26) £15.59
Shipping had to be added on.
The method of replacement was simple. Two spring clips hold the external filter in place. The internal filter bag assembly is a snug fit within the casing. I took them out and vacuumed inside. There was a little dust that had got through.
I replaced the internal filter and sealed around the perimeter with duct tape. Then I inserted the external filter and sealed the perimeter of that with duct tape too.
The filter was then hung back into position by its chains and all was OK. The fresh air flow was increased and clean air was then back in the shop.
