Flomasta Magnetic Central Heating Filter 22mm is rated 3.8 out of 5 by 4.
Rated 4 out of 5 by from Cheapest and good value Had this 2 years now. Only true menace is taking the top off. HORRENDOUS! I am an engineer and ended up using oil filter pliers. No problems then getting it off. Due to not getting this lid off for 8 months the gauze had blocked and collapsed the core inside. Will now have to get another long before I should have to. May look elsewhere. If you asked me is it worth it. Yes is the answer, now I know how to get the lid off!

Rated 2 out of 5 by from bad screw top it does collect magnetic debris, the problem arises when you unscrew it a couple of times and each time to screw it back becomes more difficult.
