How do you take care of the filters? Do you chemically clean and rotate?
I would suggest you get a 2nd set now. Clean the current ones. Keep them. Next time you drain and refill install old ones and clean new ones. I am told having 2 sets and letting them dry extends life of filters. Also, no downtime while waiting for filters to soak overnight.
I would probably stick to original filters. However, we have many customers who have upgraded. If you want the added convienence of cleaning in dishwasher, go for it.
