When you’re looking for inline water filter systems, you might often see them labeled under counter systems.
This type of filter is usually added to the supply serving your kitchen’s main cold water faucet.
Inline filters effectively serve as part of your water supply.
One of the key selling points of this type of filtration is its always-on nature. If you’re looking for a simple, user-friendly and highly efficient method of filtering the water so it’s better to drink, explore our snapshot of 6 of the best models on the market.
1) Brondell Under Counter Water Filter (UC300)
Powerful 3-stage filtration
The triple-tiered filtration with carbon blocks will remove almost all impurities clouding and impairing your water supply.
From chlorine and chloramine to cysts and lead, get rid of all these contaminants without lifting a finger. Just pop this inline system under the sink and you’re good to go.
You’ll also notice a distinct difference in VOCs and TDSs (total dissolved solids) ensuring your water is crisper than ever before.
LED faucet supplied
You will need to use the faucet bundled but it’s sleek, effective and packs a subtle LED light to alert you when it’s time to swap out the filter. When it’s time to do this, you’ll find it remarkably simple…
Easy-change filters with impressive capacity
The twist-and-seal system in place puts paid to breaking out the toolkit and lets you swap out the filters with ease even if you’re not practically inclined.
The filter is rated for 600 gallons which could give you a year of service.
Compact and space-saving system
Despite the unimpeachable filtering ability of this system, it occupies a small footprint and will slot neatly under the sink even in confined cabinets.
- Combination of highly efficient filtration and space-saving dimensions
- WQA-certified for compliance with low lead regs
- Quick connect hoses eliminate need for tasky installation
- You’ll need to use the supplied faucet
2) CuZn (UC-200) Ultra-High Capacity Under Counter Filter
You should first be aware of what this system doesn’t do. It’s not a water softener and not designed to combat total dissolved solids.
The 3-stage filter will, on the other hand, remove chlorine, heavy metals, pesticides, mold and other sediment that can contaminate your water supply.
Unlike carbon-only filters, you won’t find mold growing inside your system either due to its bacteriostatic nature.
Incredible filter capacity
Rated for 50,000 gallons, you could achieve up to 5 years of use from a single filter.
Leave your water containing everything you need and nothing you don’t
While the CuZn effectively strips away the pollutants from your water supply, you’ll leave all those beneficial minerals in place giving you a more robust and healthful effect as compared to RO systems.
As well as a 90-day money back period giving you peace of mind, the system is backed by a solid 5-year guarantee removing any niggles from purchase.
- Bacteriostatic filtration inhibits mold growth
- Leaves minerals intact while removing chemical contaminants
- Connects directly to cold water line in your kitchen
- No reverse osmosis so doesn’t reduce TDSs

Ceramic filter is easy to clean

Another space-saver, you’ll be able to slip this system under the sink even if you don’t have the most spacious storage down below.
