We all know UK tap water is generally really good and safe, and it still ranks among the best in the world for basic quality and meets strict standards. But there are growing concerns around things like chlorine, microplastics (now detected in tap water with no legal limits yet), trace PFAS (forever chemicals), lead from older pipes in some areas and other emerging contaminants that slip through treatment.

To improve our daily drinking/cooking water, we've been using two undersink filters for a couple of years: the Waterdrop 0.01 μm Ultra Filtration system in the kitchen and the Water2 Pod 2.0 (relocated to the bathroom).

I published a full head-to-head review of them here: https://renewableheatinghub.co.uk/waterdrop-undersink-uf-filter-vs-water2-pod-2-0-head-to-head-review

Both do a brilliant job removing chlorine and improving taste, plus they tackle microplastics and bacteria without needing electricity or producing waste.

So this thread is open for you to share.

What do you do to filter your water (or do you not bother)? Jug filters, undersink systems, whole-house setups or just straight from the tap? Any brands/models you rate highly for chlorine, microplastics, taste or other issues? 

Please share.

We have a Maytag American-style fridge/freezer that incorporates a water filter that uses replaceable cartridges (they last about 13/14 months for our use with 2 of us plus a very thirsty visiting grandson!). The output from this is very ‘clean tasting’ to us. The mains water entering the house passes through a Kinetic water softener first as we live in a very hard water area. Regards, Toodles.

@toodles that's a good one, and you've reminded me that our Samsung American style fridge/freezer also has a filter for ice/water (we seldom drink cold water from it though)... never really checked how 'good' the filter is.

I remember when I was in my early 20s I was introduced to a scheme for selling water filters. One selling technique was to get the homeowner to compare the water through the filter with water straight from the tap and the sales people were encouraged to make that taste test as close as possible after turning the tap off so the chlorine smell was at its strongest. It was also admitted that if someone left some tapwater for half an hour or so the chlorine would dissipate naturally.

It was at that point I realised that particular scheme was a con and, I later found out, a pyramid scheme, so I never did pursue it and do any selling.

Since then I have looked further into the reality of water filters and seen the marked variation; some are brilliant at filtering out heavy metals and pretty nasty stuff whilst others (often expensive) are only really filtering out the chlorine that’ll disappear anyway with a bit of time.

We don’t have any concerns about what’s in our local supply so don’t have a filter at all. However, I wouldn’t hesitate to install one if we moved and the supply wasn’t as good. I would, however, be doing a lot of research to get a truly effective one.
