Rated 2 out of 5 by Waste of time I have installed 4 of these over the last year believing in the words of manufacturer about dual capabilities of the filter (magnetic and non magnetic filtration). Recently I was called back on the job, 3 months after installing the boiler. The internal filter of the boiler was blocked with particles which came off the pipework and which I would expect to be trapped inside the CH filter- that's it's job- to catch the things before they get inside the boiler. This filter had just a few smal particles inside of it all of which were magnetic bits size of the grain of sand. All the bigger things got trapped inside the boiler. The system was flushed after the installation, long story how these particles got into a circulation, but that's not the point here. The point is that it looked like this thing has done nothing to prevent or at least reduce the amount of debris getting inside the boiler. Fitting this product is a waste of time in my opinion, unless it makes you, or your client feel better. I am really disappointed because it really looked like a quality product but turned out to be useless. After this experience I wonder now how other brands products "really" work, hope they do otherwise we have a plumbing scam of the decade where people are being charged £100 for a plastic jar which does nothing. 24 Sep 2015
Rated 4 out of 5 by Filter works a treat. Easy to fit with clear instructions. Does a great job and easy to remove collected gunk. I even think the boiler is warming up quicker. 28 Mar 2015
Rated 4 out of 5 by Easy fitting filter This is one of the easiest filters to fit on the market because the whole filter body detaches. This gives clear access to the nuts to allow fitting of the valves, then the adaptor then the body It also doesn't need loads of headroom to remove a magnet like some others do, so can be fitted on more compact spaces. It is fully adjustable to suit any angle/direction of flow of pipe 29 Jan 2015
Rated 5 out of 5 by exceptional value product Have fitted a couple off these and cant believe anybody would fit a new boiler without one off these installed ,after all you wouldnt buy a new car and put your old cars dirty oil into it which is what your doing if you fit a new boiler without a filter,totally recommend this filter as it removes all impurities not just the magnetic ones 30 Dec 2014
