Frequently Asked Questions
Q: With this whole house system, do I still need to install a water softener if my water is
very hard?
A: Yes, a water softener is needed if your source water has a high level of hardness,
usually with TDS higher than 700 PPM. Hard water can reduce the lifespan of whole
house water filter cartridges. The harder the water, the greater amount of scale buildup
occurs, and the sooner the filters get clogged.
This whole house water filter can remove 95% of sediment, chlorine, rust, pesticides,
herbicides, industrial solvents, VOCs, and various other contaminants that a regular
water softener can't; however, it does not soften your water. It is recommended that
you install this WGB32B whole house system after your water softener to achieve
optimal performance if you have hard water.
To determine which product best suits your needs, it is recommended that you get a
professional water test done prior to purchase to identify the main issue of your source
water.
NOTE: Water Softeners and whole house systems usually do not lower the TDS level of the water. An
additional Reverse Osmosis system may be necessary for your drinking water. Please consult iSpring
professionals prior to purchase if you are unsure of which product will meet your needs.

Q: What type of Whole House Water Filter do I need?
A: If you are on municipal water that isn't contaminated with heavy metals like iron,
manganese, and lead, the WGB32B is the system to go with. Naturally occurring metals
are commonplace in most well water sources, however, and that is where the
WGB32BM or WGB32B-PB earns its keep. If you are on well water or have heavy metals
in your municipal water supply, you may want to consider the WGB32BM or WGB32B-
PB over the WGB32B. For removing the common contaminants found in the majority of
municipal water supplies, however, the WGB32B fits the bill.

Q: What flow rate should I look for?
A: Measured in gallons per minute (GPM), flow rate determines the amount of water
available to run your shower, toilet, hot water heater, dishwasher, etc. When calculating
your requirements, look at the demand ratings printed on your appliances and toilet.
Depending on the size of your house and family, your water flow rate requirements may
range from 5 to 40 GPM.
