Aqua Optima by LAICA Evolve+ Hard Water Limescale Filter Cartridges,3 Pack | Fits Brita jugs and reduces limescale, chlorine, impurities with advanced filtration to help protect kitchen appliances.

I'm in a hard water area and I did not like the taste of the water. Buying bottled water costs more than this product I also brought the jug and together they work well. Easy to fit and it lasts a full 30 days before needing to change the filter. There is no taste once the water is filtered and it's lovely and clear. It also keeps the kettle clean from limescale and my cat loves drinking this water. No complaints

I have bought water filters for many years (like 20+ years). But these actually are the best.They’re for hard water, in our region it’s really hard. Usually when I used other filters, I’d be seeing limescale start to build up pretty instantly.I started using this filter on Wednesday. It’s now Saturday and still NO LIMESCALE!And we drink a lot of hot drinks daily!Even my sons who normally don’t care about drinking filtered water vs tap water, have said commented on how clean tasting this water is.I loved how simple the process was for fitting the filter too. It looks a bit odd compared to the original Aqua pura ones or Britain’s maxtra+ ones, but it fitted easier. When conditioning it ready to fit, the process was less convoluted than the others too. Took only 1 min of running it under the tap water. Then 2 changes, done.Will buy again, as long as Amazon still stock them

Very effective in a hard water area.No limescale in kettle since using these cartridges. Highly recommend.

Excellent product. Easy fit and pleasant taste.

I found them a little slow to filter, even a 1.75-litre jug, but they are good value for the price and easy to fit, and if you are in a hard water area, they do soften the water and improve the taste, and you need to filter two kettles full before you can use the third filtering but I think that is par for the course for most filters and they don't leak, fitting nice and tight.

I tested unfiltered and filtered water with test strips and the difference was huge. It went from the hardest level of the strip to the softest. We'll see how it tests 30 days from now, but it seems to really help.

Great for limescale as we're in a hard water area, but the taste isn't so nice. I shall be going back to Brita next time

Works great. Saves my electric kettle, coffee maker and iron from furring up. Remember, if you don’t use a water filter, your kidneys are the filter.

Excellent,! All set up now..
