Question 1

How much does a reverse osmosis system cost to install?

Accepted Answer

Under-sink RO systems range from $400-$1,200 for 4-6 stage units, plus $150-$300 for professional installation. Whole house RO systems cost $2,500-$8,000+ depending on capacity. Basic systems start around $500 total, while premium systems with remineralization and UV sterilization cost $1,500-$2,000 installed.

Question 2

Does reverse osmosis remove fluoride?

Accepted Answer

Yes, reverse osmosis removes 95-98% of fluoride from water. The RO membrane effectively filters fluoride ions along with most other dissolved contaminants. This makes RO one of the most effective home treatment methods for fluoride removal, superior to standard carbon filters.

Question 3

How often do RO membranes need replacement?

Accepted Answer

RO membranes typically last 2-4 years depending on water quality and usage. Pre-filters should be changed every 6-12 months to protect the membrane. Post-carbon filters need replacement annually. Regular filter maintenance extends membrane life and maintains water quality. We offer filter subscription services for convenient automatic delivery.

Question 4

Is reverse osmosis water safe to drink?

Accepted Answer

Yes, RO water is extremely safe to drink. The multi-stage filtration process removes 95-99.9% of contaminants including bacteria, viruses, heavy metals, pesticides, and pharmaceuticals. Some systems include remineralization filters to add back beneficial minerals. RO water is purer than most bottled water brands.

Question 5

What's the difference between RO and water filtration?

Accepted Answer

Standard water filtration uses carbon and mechanical filters to remove chlorine, sediment, and some chemicals. Reverse osmosis uses membrane technology to remove 95-99% of ALL dissolved solids including salts, minerals, heavy metals, fluoride, and microscopic contaminants. RO provides higher purity but produces wastewater, while standard filters are faster and don't waste water.

Question 6

How much water does reverse osmosis waste?

Accepted Answer

Traditional RO systems waste 3-4 gallons for every gallon produced (75-80% wastewater). Modern efficient systems reduce this to 1:1 or 2:1 ratios. While this seems wasteful, an RO system uses less water than regular bottled water consumption when considering manufacturing and transportation. Wastewater can be collected for plants or cleaning.

Question 7

Do I need a storage tank for RO water?

Accepted Answer

Most under-sink RO systems include a 3-4 gallon pressurized storage tank because RO filtration is slow (typically 50-75 gallons per day). The tank provides immediate access to purified water. Tankless RO systems exist but require higher water pressure and produce water on-demand at slower flow rates.

Question 8

Can RO systems remove lead from water?

Accepted Answer

Yes, reverse osmosis removes 95-98% of lead from drinking water, making it one of the most effective home treatment methods for lead contamination. The RO membrane filters lead particles and ions effectively. For homes with lead pipes or high lead levels, RO systems provide critical protection.

Question 9

Does RO water taste better than tap water?

Accepted Answer

Yes, RO water typically tastes significantly better because it removes chlorine, sulfur, minerals, and dissolved solids that affect taste. Many people describe RO water as crisp, clean, and neutral-tasting. The final carbon polishing filter enhances taste further. RO water quality rivals or exceeds premium bottled water brands.

Question 10

Are RO systems difficult to maintain?

Accepted Answer

RO systems are relatively low-maintenance. Pre-filters need changing every 6-12 months (simple twist-off replacement), membranes every 2-4 years, and post-filters annually. Total annual cost is typically $75-$150 for filters. We offer maintenance plans with filter delivery, reminder service, and annual system inspection to ensure optimal performance.
