A reverse osmosis home water filtration system purifies tap water using a simple DIY set-up and reduces dependency on plastic water bottles. Quality systems can remove up to 99 percent of total dissolved solids (TDS) from the water supply and provide fresh drinking water free of contaminants.

Here are a few reverse osmosis water filtration systems to consider:

1. APEC ROES-50 Reverse Osmosis System

This five-stage filtration system removes lead, chlorine, bacteria, copper, fluoride, and iron from up to 50 gallons of tap water per day. The filter is typically set up under kitchen sinks and includes double carbon blocks for enhanced performance. This system does not have a remineralization filter, which means the water may taste “flat”.

The APEC ROES-5 includes a four gallon storage tank, faucet dispenser, filter set, tubing, and an installation kit. Filters stages one through three can last up to 12 months, and the reverse osmosis membrane and carbon filter can last between two and four years.

2. Waterdrop D6 RO Water Filtration System

The benefits of this system is reduced water waste, smaller carbon footprint, easy maintenance, and access to real-time insights on water quality. The installation process takes less than 30 minutes and families can enjoy up to 600 gallons of filtered water per day.

3. Home Master Artesian Water Filtration System

This system features easy-to-change filter cartridges that don’t require any tools, since the canister and filter media are integrated into a single unit. However, the lack of housing means the modular filters and tubes are exposed under the sink, rather than being contained in a sleek housing unit.

4. AquaTru Countertop Water Filtration Purification System

Homeowners that need extra space under the kitchen sink can store this system on the countertop and plug it into a wall outlet. Filter life is 600 to 1,200 gallons of purified water. The system doesn’t require any plumbing, but is limited to a three-quart purified water tank.

5. iSpring 6-Stage Under Sink Reverse Osmosis System

This is a six-stage filtration step that includes an alkaline remineralization filter. Filters for stages one through three will last three years, while the reverse osmosis membrane will last two to three years. The post-carbon filter should be replaced annually.
