Great service. It’s was delivered very quickly! Highly recommend!
Lovely company to deal with and prompt delivery. I'm in the scottish highlands and they recognised that post is better than courier for rural deliveries.
A wide range of filters ( and UV bulbs) available. Extremely prompt delivery at a very competitive price. Great follow up customer care too.

I bought the wound sediment filters. I found the filters arrived very quickly. It was later followed by a courtesy call to make sure the product was received and correct. Just fitted the filter and it is working very well. Very friendly customer service, would not hesitate to reorder from them in the future.
