Seller feedback (35,947)
- o***d (34)- Feedback left by buyer.Past monthVerified purchaseReceived items as described. We'll boxed with no damage to filters, good condition as filters were individually wrapped in cellophane. Appear to be a good quality as I have used these cartridges for whole home water filtering for a few years. Received fair price on 6 filters and they were packaged and delivered clean and ready to use. Seller provided tracking information and delivery date was fully accurate.
- m***t (68)- Feedback left by buyer.Past 6 monthsVerified purchasePackaging wasn't great, there were holes in the shipping box and no additional protection for the filters. Thankfully none of the filters were damaged. Overall everything is as described and there are no differences from other filters I've bought. Shipping was fast and the price was reasonable, thank you!
- 0***2 (261)- Feedback left by buyer.Past monthVerified purchaseBeen using these filters from this seller for years. Great value and they work perfect. Arrived in excellent condition. Had a shipping issue (not the seller, but the shipper) and seller was wonderful communicating and fixing the issues.
- k***t (205)- Feedback left by buyer.Past 6 monthsVerified purchaseThese filters are great and the price is good. The seller ships fast and the packaging protect the filters. Second time I have purchased from this seller and they do not disappoint.
- a***p (362)- Feedback left by buyer.Past monthVerified purchaseThe first package was delivered by the USPS damaged, and I contacted the seller. They immediately gave me the option of either a refund or resending a replacement package. The replacement package was quickly sent out by UPS and arrived safe. Excellent communication by the seller. The instructions on the new filter say rinse 5 gallons of water before use, I found it easier to use a garden hose for a few minutes.
- 0***e (200)- Feedback left by buyer.Past monthVerified purchasePackage arrived on time, In good condition, and communication was good also. As described too.I would recommend this seller.
