1. Do I have to pay for a plumber to change the filter?
Aquasana shower systems are designed for easy replacement, and you can do it yourself in minutes. No plumber is necessary. If you have any questions or need assistance, our technical support representatives at 877-996-2875 can walk you through the installation process.
2. How often do I need to change the filter?
The filter should be changed every 10,000 gallons. 10,000 gallons at 2 1/2 gallons per minute = 4,000 minutes of showering. You can take:
• 400 10-minute showers
• 267 15-minute showers
• 400 10-minute showers
• 267 15-minute showers
3. How much chlorine does the shower filter remove?
Aquasana shower systems are tested to remove 90% chlorine for 10,000 gallons.
4. What is the flow rate of the shower filter?
The optimum flow rate for the filter and shower head is 2.5 gallons per minute.
5. Can I use my own shower head or hand-held wand with the shower filter?
Yes, you can use your own shower head. The AQ-4100NSH is the correct model for individuals using their own shower head. Just remember the shower head needs to have the same 1/2 inch connection as standard shower heads and the ideal flow rate would be 2.5 gallons per minute. If your shower head processes more than a 2.5 gallon flow rate per minute, the quality of filtration may degrade slightly. Increasing the flow rate by changing the shower head reduces contact time with the media and will reduce the filtration quality. If you decrease the flow rate by using a different shower head you will not impact the performance of the system. If you use a shower head with a shut-off switch you could cause damage to the system.
6. Can I use the shower filter for drinking water?
Drinking some of the water during your shower poses no health risk. However, Aquasana does not recommend that you use the shower system as a primary drinking water source since it is not designed as a drinking system and has only been tested under shower conditions and regulations.
7. Can I hook the shower system up under a constant pressure application?
No, the shower system is designed to allow the water to consistently pass through the system as it filters. If the system is under constant pressure and unable to release the pressure introduced into the system during filtration, damage can occur to the unit.
8. What is the shower filter media made of?
Aquasana’s Shower Filters are made from a patented copper-zinc media and coconut shell carbon. Natural coconut shell carbon filters out chlorine and other harmful chemicals while copper-zinc media further reduces chlorine and enhances water pH balance.
9. I’m allergic to coconut. Can I use the shower filters?
Yes, you can use Aquasana’s Shower Filters if you are allergic to coconut. The carbon shell is pure carbon with nothing remaining from the coconut. We use coconut carbon because it is the hardest, most dense source of carbon and has the smallest cells to maximize filtration.
If you have a very severe allergy to coconut, we recommend consulting your physician before use.
