Frequently Asked Questions
What does “GPD” mean, and how much water will these systems provide daily?
“GPD” stands for Gallons Per Day. It tells you how much purified water a system can produce in 24 hours. For example, the PuroSmart PSCT50 offers 50 GPD, which is plenty for typical household drinking needs.
What’s the difference between a regular filter and a Reverse Osmosis (RO) system?
Regular filters catch larger particles and some impurities. RO goes further, using a fine membrane to remove most contaminants, including dissolved solids. This makes water exceptionally pure. The Dreo and Bluevua are RO systems, while the Purewell filtration system is not.
How often do I need to change the filters, and how much does it cost?
Filter replacement depends on the system and your water quality. For RO systems, some pre-filters might need changing every 6-12 months, while the RO membrane lasts 1-2 years. Check the PuroSmart specs, as filter lifespans can vary. Expect to budget around $50-$100 annually.
“What does the ‘efficiency ratio’ (like 3:1 or 4:1) mean for these systems?”
The efficiency ratio indicates how much wastewater a system produces for every gallon of purified water. A 4:1 ratio means for every 4 gallons in, you get 1 gallon purified and 3 gallons go to drain.. Higher ratios (like 4:1 in the SimPure) are better because they mean less water waste.
Will these countertop systems fit my kitchen faucet, and how easy are they to set up?
Most of the systems are designed as countertop units and don’t connect to your faucet except for drain water.. Systems like the PuroSmart have a faucet quick-connect. Check available space before you purchase to make sure whatever you choose will easily adapt in your space.
