Customer Questions & Answers
-
Question:
How long does the filter life last?
Answer: The Culligan D-30A filter has a filter life of 12 months or 1000 gallons, depending on usage and filtration load. -
Question:
What substances does the filter reduce?
Answer: The filter reduces giardia, cryptosporidium cysts, lindane, atrazine (a pesticide and herbicide), asbestos, mercury, chlorine taste, odor, and sediment. -
Question:
Is the filter compatible with other filtration systems?
Answer: No, it is compatible only with the Culligan US-550, US-600A, SY-2000 and SY-2100 filtration systems. -
Question:
After 6 months of installation, I can see some particles in the water that are larger than 0.5 micron. What could the problem be?
Answer: You might have received a defective unit or the filter might be disintegrating inside the housing. However, there should NEVER be visible particulates in your water with this filter as it is NSF certified. Please visit the NSF website for verification. -
Question:
Will this work in 2.5 x 10” filter housing?
Answer: Yes, it will work on that housing. It works well with both well water and rural water as long as you change the filter once a year or twice a year whichever is appropriate for your usage. -
Question:
Wondering how to fix the restriction?
Answer: What restriction? There is no restriction. Do not drill these filters or make any alterations as it might damage the filter. If you have any issues, you can contact the customer service of the manufacturer. -
Question:
Can this Culligan D-30A level 2 drinking water replacement cartridge be used as a replacement for D-15 filter?
Answer: Yes and no. Culligan offers two types of filters-D30A with an effective duration of one year and D15 with an effective duration of three months. You can use whichever is appropriate for your usage. -
Question:
1 inch center?
Answer: It is about 3/4 inch. -
Question:
10.25"H x 5.6"W x 8"D... what? this does not match or fit my US-600A housing
Answer: Those numbers are incorrect. The filter measures approximately 9 and 3/4 inches in length and 2 and 3/8 inches in diameter. Please measure the filter provided to you and ensure it is the correct one. -
Question:
Is this really a Culligan filter or another brand?
Answer: Yes, it is a Culligan filter. It carries the Culligan name on the label and is identical to the filter available from authorized Culligan dealers. However, it might be available at a lower price here.
