Whole House Water Filter and Filter Housings FAQs

Whole house water filters should be installed at the water main before the water heater for optimal performance. Carbon media in particular performs better at cold temperatures.

Whole house water filters do not directly affect the pH of water. Removal of certain minerals and contaminants by the water filtration system may decrease the overall pH of the water, but in general, to address pH issues it is best to use an alkaline filter or a distillation system.

No. Traditional water filter systems such as SpiroPure SP-WH200 and SpiroPure SP-WH300 will not remove nitrates or nitrites from water. To reduce nitrates and nitrites, a reverse osmosis system, ion exchange system with a strong base anion resin, or distillation is needed. We do have SpiroPure Reverse Osmosis Systems available.

Reversing the water flow direction is not advisable or recommended. Doing so will void the warranty as parts can be damaged in the process leading to potential leaks and water damage.

SpiroPure filter housings and any filter housing you encounter on the market will not have a flow rate. This is because the expected flow rate will be determined by the filter cartridges you choose to purchase and install inside of the housings.
