Thank you! ### ⭐⭐⭐⭐⭐ Save money, verify need to change filters *by M***I on September 6, 2023* Purchased and installed a Brondell Circle RO system in August 2022. We're still using the original cartridges, I purchased a replacement set just in case and they are still sealed in the box. Changing them every 6 months is (probably) a waste of money. First, buy yourself a TDS meter (not a referral link, plenty of others on Amazon but this is the one I got- https://www.amazon.com/gp/product/B07QLZ6DT5 ) and test your water from the faucet versus out of the reverse osmosis filter. Our water is normally around 60 ppm, from the Brondell it is about 6-7 ppm. After a year it is still 6-7 ppm TDS. At exactly 6 months and again at 12 months the "change filter" light on the faucet started blinking. I don't think it is based on water usage, it is on a timer. All I do is remove the battery, wait 30 seconds and reinstall. Your mileage may vary, obviously our faucet water is naturally pretty low on contaminants (only reason we got the RO is that 2 of those contaminants are arsenic and manganese so it's nice to reduce those to safer levels) so if your tap water has more stuff in it your filters may get clogged up faster. But if you have a TDS meter showing you the filter is doing its job AND your water flow is not slowing down changing the cartridges is unnecessary. Hope that helps someone concerned about the high cost of these oem filters. ## Frequently Bought Together - Brondell RF-20 Water Filter Replacement for Circle, Sediment and Carbon Block, Under Sink Reverse Osmosis Filtration System, Lasts 6 Months - Brondell RF-40 Membrane Water Filter Replacement for Circle Under Sink Reverse Osmosis Filtration System, Lasts 6 Months - Brondell VivaSpring Compact Shower Filter, Polished Chrome – High Output, 100% High-Purity KDF Filtration, With FF-30 Filter Cartridge, Filtered Shower Water for Healthier Skin & Hair --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/19716444-rf-20-water-filter-replacement-for-circle-sediment-and-carbon](https://www.desertcart.es/products/19716444-rf-20-water-filter-replacement-for-circle-sediment-and-carbon) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-04-23*
