What heating system system filters are you currently using?

I always avoided the original Magnaclea/Magnaleak like the 'Rona virus. Went through a phase of fitting the Spirovent brass filter before they added the outside magnetic sleeve. However, the sleeveless Spiros were crap at collecting debris - hence the need for them to add the sleeve as an afterthought. When the Magnaclean Pro 2 came it it looked good, but I left them for a while to see what the opinions in the trade of them were before I jumped in and started installing them.

When I started fitting the Pro 2 I haven't looked back. Great piece of kit - bit pricier than some others, but as the saying goes - "filters are cheap - blocked ch systems are expensive". Even got one on my own ch system and it seems to catch most debris. Important as some of the rads are nearly 60 years old. The Pro 2 is easy to fit, especially because the upper compression joint is a slip joint which helps if there isn't much give in the pipework. There's a mini version of the Magna if space is really tight. Have also fitted the Fernox Boiler Buddy is odd situation where can't get a standard filter in. They fit inline between two pump valves. Probably not as good at filtering as the Magna, but better than nowt.

Some Magnaclean lids, especially the original version, can be a bit tight to turn. Smear of sillycoon grease on the cap threads sorts this.
