Check price on AmazonFrequently asked questions
Are both filters NSF certified?
Yes. Both the Waterdrop WDS-F27 and the Icepure RWF4700AC carry NSF 42 certification, which means they are certified to reduce aesthetic impurities including chlorine taste and odor. The WDS-F27 also lists NSF 372, confirming its materials meet lead-free standards. Neither listing claims NSF 53 or NSF 401 certification, so neither is certified to reduce health-related contaminants such as lead or pharmaceuticals.
Which filter costs less per replacement?
The Icepure RWF4700AC works out to roughly $9.91 per filter based on its three-pack price of $29.73, while the Waterdrop WDS-F27 runs about $12.50 per filter as a two-pack at $24.99. Over a year of quarterly changes, that difference adds up to several dollars in favor of the Icepure. Prices on Amazon fluctuate, so check current listings before you buy.
How do I know which filter fits my refrigerator?
The safest approach is to look up your fridge's model number in the manufacturer's owner manual or on the filter door label, then cross-reference it against the compatible models listed on each product's Amazon page. Both filters are third-party replacements designed to fit specific OEM housings, so dimensions matter: the WDS-F27 measures 4.37 x 2.2 x 8.97 inches while the RWF4700AC measures 2.1 x 2.1 x 7 inches, indicating they target different fridge platforms.

How often should I replace a refrigerator water filter?
Most refrigerator manufacturers recommend replacing the filter every six months or after 200 to 300 gallons of water, whichever comes first. Households with high water usage or lower-quality municipal water may benefit from changing the filter every three to four months. Your fridge's indicator light, if it has one, is a practical reminder, but it is not always calibrated to actual usage, so track the date of installation as well.
