Aqua Optima Water Universal Filter Cartridge, 30 Days (12 Months Supply), Compatible with Brita Classic,5 Stage Filtration System Reduces Chlorine, BPA Free, White (Packaging May Vary)

Great filtration, good value, on my second box now

Fits my lazy spar hot tub

I liked the price however they’re not a patch on the universal filters I used to buy from Wilko. They are slow to filter and they don’t seem to improve the quality of the water.

The replacement filters fit the unit perfectly and seem to be doing a great job of purifying the water.Great value compared to the genuine item

Good price at the time I bought these filters and seem fine.

i havent had to use one yet, but the one in my water heater works well

Do the job as well as more expensive products

These have been very good.
