Abstract: The invention is an apparatus and method for treating fluid in a pool, spa, or water tank, etc., using ozone and treated air. A fluid filter is placed in an auxiliary reservoir or a smaller fluid tank located in or next to the pool, spa, or main water tank. An ozone generator pumps a combination of ozone and air into the smaller fluid tank.

More specifically, a vertical lift tube is placed beneath the smaller fluid tank so that the open top of the lift tube is within the smaller fluid tank. Fluid from the main reservoir is piped to the bottom of the lift tube. Ozone and air from the ozone generator is also piped into the lift tube near its bottom. The fluid flows through the filter due to the effect of ozone and air bubbles released by a diffuser at the bottom of the lift tube.

Abstract: Provided is a filtration system for filtering contaminants and impurities from a coolant, such as water, applied to an air conditioner unit for cooling the air conditioning unit to increase the efficiency thereof. The filtration system filters the coolant to achieve a desired purity level to allow the coolant to mitigate corrosion or particle buildup on the air conditioning unit when the coolant is applied thereto. Along these lines, if the purity level is too low, the contaminants present in the coolant may corrode the air conditioning unit. Conversely, if the purity level is too high, the coolant itself may react with the air conditioning unit, which may lead to corrosion or other structural issues. Thus, the filtration system is specifically configured and adapted to purify the coolant to achieve a purity level within a desirable purity range.
