Rating: - Good Replacement for Honeywell
Note: The replacements have a carbon/charcoal filter attached to the front. The one that came with my HEPA filter didn't have a charcoal filter but was advertised/described as being a permanent filter which could be refreshed/cleaned by using a vacuum cleaner to suck up the collected dirt/dust. Not sure if possible to vacuum clean if the charcoal filter is in front of the HEPA filter folds.
Rating: - Perfect job
This filter was hard to find on the internet, and impossible locally, but fit perfectly in the air cleaner. The price is high, in my opinion, and discourages replacement when the light on the unit indicates replacement is required.
Otherwise, it works well.
Rating: - effective but pricey
It's a great filter, if however you are planning to use it next to an ashtray, please bare in mind that it will capture the smoke but not the odour. It is very successful at removing all particulates from the air.
