Fernox TF1 Total Filter

Like most opinions on here not the best made filter. Apart from seals leaking after working on them , they have a pretty poor magnet, not the best out there.

Wouldn’t personally purchase one of these over an ADEY Magnaclean but have installed a few for customers now. Nothing massively wrong with the unit just generally not as good And not as easy to use

Not the best bit of kit on the market, have an issue with over tightening which results in some small leaks, best to only hand tighten, bit overpriced for what it actual does

Not my favourite filter on the market, find the build quality to be poor, not the easiest to install and overall very fiddly with all the different type of washers/o rings, often get a small weep on it

By far one of the worst filter I have ever come across. Awful to service as valves and seals leak. Even on replacing seals and following there instructions they leak. I actively take them out if I see one installed now and replace with a better quality filter.

Used to use these a lot but they all leaked after a while. They would need to be tightened constantly so stopped using and went for the magnaclean instead

I have tried these filters in the past and everyone has leaked it different places. I wouldn’t buy one ever again and the price is not cheap either. Not good for the money.

I used to fit these filters when they first came out hoping that they would be better than magnaclean. At the time magnaclean filters had a problem with the screw cap access to the magnet, the cap over time distorted. Low and behold the same thing happened to the tf1 after a year and also the filters leaks from adjustable base. Adey (magnaclean) have addressed the issue with the cap. I would highly recommend the magnaclean Pro 2, great bit of kit and worth the cost.

Now these are not as good as other brands. Most show signs of leaking or leakage and most of you even look at them start to leak. Would not recommend

terrible filter i will never choose to fit 1 of these again, big ugly bulky product and worst of all id say 90% of the time will leak when you carry out the annual cleaning of it

Unfortunately they have just not got this filter right. Leaks when cleaned from the top and fernox do not recommend this now, without fitting a new service kit after...
more hassle than it’s worth. Fernox have great products but unfortunately their system filter is not one of them

i used to fit a lot of these, easy to install, ieasy to access drain point and it performs reasonably well.
However i had 6 or so leak after a couple of years i have since lost my confidence in the product

Installed loads of these now, in my opinion one of the best filter out there, handy drain point and vent too

Used to fit these all the time easy to fit in different situations but after a while they started to leak quite badly so changed to different model

I keep having yo go out and remove these because they leak from the top, isolation valves and drain off.

Don't like this filter if I'm honest, ok going in and fitting but seem whenever you touch them after install they leak like a good un

Following on from some other reviews they can move about a bit when fitting and servicing, so you need to re tighten the joints as they can leak, saying that it’s s good product as it filters a lot of sludge from the system, and is easy to install.

Fitted loads of these filters in the past but most have been taken out now because they leak and most places do not stock the service kits.

Not bad not had a problem but only fitted a couple recently. Would fit more for the right price. Not had any leaks as yet

Fitted a good few of these and almost every one has leaked and been replaced. They are easy to fit and work well but the build quality lets them down.

Great value for money for a well built filter. Easy to install and has good features. It’s my customers favourite

Easy to fit and does collect sludge on system. However, joints will leak on this within a couple years of installation (usually).

The tf1 is a cracking filter I
Easy to install
Great for dosing chemical inhibitors
Good quality Boiler protection

Don't like these at all!! As soon as u touch them they start to leak. Had also far to big to get under a boiler most of the time.

Not a fan of this filter. Had alot of issues when trying to clean them out. The last thing you want on a service is getting caught up trying to repair these.

Easy to install and clean out every year via the drain at the bottom.

Just had too many leaking units in the past to recommend this to anyone. Always carry a service kit just in case I come across one

Fernox do have some great products just not this one

Decent filters from new for a short period of time, fitted a few and no issues whilst installing one but I've been out to a few leaking after only being in 8-12 months or so and always carry a service kit on the van if you ever touch one!

This product is pure crap if you see one fitted don't touch it cause it will cause you a head arch and a nice wet puddle for the customer.

Would avoid fitting these filters awful product, I've changed so many of these for leaking! Personally always fit brass filters and no problems!

I found the biggest downside was the size. I personally have never had one leak. But it's Omega power now.

Leakey expensive . Have had issues with every one I've bought. I'm iftting a cheeper one that gives me far less bother or it's all metal brother . Now that's a good filter

Had nothing but problems with these, the top sealing washer is a pain for leaking after cleaning and cleaning is a must as the drain point at the bottom doesn't work properly. Tried on a number of times but when I have checked after to see how will it cleans it always has crap left on there!

Glad they made the Omega. This product is nearly as bad as the boiler buddy they brought out. Make sure you have new seals if you ever need to remove the lid

Good old leaky tf1, I thought the magnaclean was bad, fair enough it picks up ok, but still not the best, it's big and ugly and leaks from everywhere, the plastic cap/ISO lever is always worn so you have to use grips, I wouldn't buy or sell one of these, maybe the omega, for now I will stick to spirotrap with spirovent on new installs and the magnaclean on upgrade work, only because they really pick up the sludge and muck.

I am not a fan of these boiler filters, they have a tendency to leak, I also don't like that there and so many nuts to tighten on install, just more places to leak from in the future

The early ones of these were horrible, always leaked and not great aesthetically. They seem to have solved the problem with the seals failing all the time but still not a product I'd chose to install

I have installed hundreds and hundreds of Fernox TF1 filters , The early ones had some issues with leaks but the backup and support from Fernox was brilliant, The newer ones of these are very good and we haven't had any issues with them,

Used to use these but found the seal to be troublesome, could give you a right headache on servicing

Good filter well built . Not had any issues

Terrible to service they always leak. Hate them. I like the new omega though

Used to fit these daily in a green deal contract. Still using brass nuts on plastic threads-that should tell you all you need to know. They rarely seal the lid after the first service. No thanks magnaclean pro2 all the way

I've never installed one of these filters but have cleaned alot of them out. They always leak so now I carry a new seal kit round with me. I wouldn't recommend these to anyone.

Always leak avoid

Not keen on them. Tend to leak around top seal and find magnet to be too small

Fitted 2 so far, no problems yet

Leak leak leak

Great product

Where the plastic meets the metal can crack. Also washers go on these a lot. I love the drain of at the bottom making it easy to service.

bit big and sometimes leak after you have worked on them on bits you didn't touch
