Prof. Benjamin Murphy, Ph.D.The first step in finding the best house water filtration system is to test the quality of your water system. I know this from the experience of installing a faulty system that did not remove arsenic from the water. This should be done by identifying certain contaminants, such as arsenic and bacteria, before selecting your filtration equipment. Additionally, your geographical location, water supply, and project budget will determine the optimal solution for your house.
Select a system with these important considerations: The size of house holds indicates be needed capacities. The nature of contaminants indicates preferred technology. The space available under sink affects method of installation. There is a complete difference in maintenance required for any of the methods. I recommend a professional water test every other year.
Contaminant Profile
- Test for heavy metals, microorganisms, and chemicals
- Reverse osmosis handles arsenic and lead best
- Carbon filters excel at chlorine and VOC removal
Household Water Usage
- Calculate daily consumption for proper sizing
- Small families may use countertop systems
- Whole-house systems suit large households
Installation Space
- Measure under-sink clearance for RO units
- Countertop distillers need electrical outlets
- Wall-mounted options save cabinet space
Long-Term Costs
- Factor filter replacement frequency
- Electricity for UV/distillation adds expenses
- Wastewater ratios impact utility bills
Proper installation guarantees maximum efficiency. Place units away from any heat source that could damage or destroy the filters. Secure connections prevent leaks that created the flooding in my basement. Follow directions as provided by the manufacturer. Consider professional help for the complex under-the-sink equipment.
Diligently keep your system. I change my filters every year on my birthday. I clean the housings once a quarter to prevent bacterial growth. Monitor the water pressure of your RO units. Check the water quality after the filter has been changed. Regular maintenance will significantly extend the equipment's lifespan.
Consider expenses beyond the initial purchase. For example, my RO system was a good long-term investment because, although it had a higher initial cost, it had lower operating costs. Compare electric usage and filter costs. Calculate wastewater ratios. Consider the cost of professional tests. Prepare a budget for unexpected repairs, such as pump failures, to avoid financial strain.
