Cleanable Evaporative cooler

tritous

I used to have a very good evaporative cooler which had all the features I needed: removable water tank (important for cleaning it), it used a gauze on a conveyer which dipped it in the water pulling the airflow through the gauze to evaporate (filtering, but also meaning no pumps which fail easily) and an ionising filter on the output which helped with anything that got past the water filter, all with a decently powerful fan.
Sadly it died after 5 years use, and the replacement (without a removable tank and with a pump) failed after a year due to lime buildup and was never as good.

I'm struggling to find anything with these features as the original (especially removable tank) was an own brand by B&Q and they no longer make it. I'm not in favour of putting a hole in the wall for an Air-con.

Are there any recommendations on decent evaporative coolers still on the market for UK?
