Frequently Asked Questions
What does “GPD” mean in the product descriptions?
“GPD” stands for Gallons Per Day. It tells you how much purified water the system can produce in a single day. So, a system with 600 GPD like the Frizzlife PD600-TAM3 makes more water than a 75 GPD system like the APEC ROES-PH75.
Why choose a tankless system like the Frizzlife PD600-TAM3 over one with a tank?
Tankless systems save space and provide on-demand water. Since there is no tank, you do not have to worry about potential contamination, and the water pressure stays consistent. A traditional tank system, like the AMI AAA-RO-100, stores a reserve.
What is “remineralization,” and why is it important?
Reverse osmosis filters remove almost everything from water, including natural minerals. Remineralization adds healthy minerals back into your water, like calcium and magnesium, improving the taste and adding health benefits. The Frizzlife PD600-TAM3 and APEC ROES-PH75 both feature this.
How do I know which system fits my needs?
Think about your household size and water usage. For larger families needing lots of pure water, look at models like the Frizzlife PD600-TAM3 or iSpring RO800G+UVF8. Smaller, more budget-conscious homes can be great with the AMI AAA-RO-100 or iSpring RCC7.
What does NSF certification mean?
NSF certification means that the system has been independently tested and certified to meet strict standards for safety and performance. Models like the AMI AAA-RO-100 and iSpring RCC7 carry this certification, giving confidence about the water quality and system integrity.
