FAQ for Our Water Filtration Products
Q: What system should I choose for city water vs well water?
A: City water often needs sediment and carbon filtration for taste and odor. Well water often requires sediment filtration and may also require UV disinfection.
Q: Whole house vs under sink, what is the difference?
A: Whole house filters water at every tap. Under sink filters for drinking and cooking water at one sink.
Q: What does UV purification do, and when do I need it?
A: UV disinfects water by inactivating microorganisms. It is most common when well water is used or when disinfection is needed.
Q: How often do I replace cartridges, RO filters, and UV lamps?
A: Replace filters on a schedule based on usage and water quality. UV lamps are typically replaced yearly.
Q: Will filtration reduce water pressure?
A: It can if the system is undersized or the filter is clogged. Proper sizing and timely replacement help maintain flow.

Shop by Water Problem
Get started by choosing your water type and goal, then shop for the system or replacement part that matches your home, business, or job site.
Chlorine Taste and Odor
If your tap water smells like a pool or has a chemical taste, a carbon-based filtration system can help reduce chlorine and improve overall taste and odor. Great for city water and homes that want better water at the kitchen sink or throughout the house.
Shop for Carbon Filters
Sediment and Particles
Do you see grit, cloudiness, or buildup in faucets? This can be a sign of sediment, such as sand, silt, or rust. Sediment filtration helps trap particles to protect plumbing, appliances, and downstream filters, while helping maintain cleaner, clearer water.
Shop for Sediment Filter Kits
Hard Water Feel and Scale
Does soap not lather well, spots appear on dishes, or is there scale buildup on fixtures? Hard water minerals may be the cause. Water softeners:
- Help reduce mineral buildup
- Improve cleaning
- Support longer appliance life
Microbial Concerns
- If you rely on well water or want an added layer of protection
- Helps inactivate microorganisms
- Commonly paired with sediment filtration to allow the light to work effectively
Clean Drinking Water
- A dedicated drinking water solution with multi-stage filtration
- Designed for a high level of purification at one faucet
- Ideal for improving taste and clarity for drinking, cooking, and ice
I had my bathroom redone and installed a built-in hand shower at a level accessible from my shower stool. This filter easily fits in the narrow space behind the nipple.
They don't get your order out overnight like Amazon (if that's what you're used to), but I did get it within a reasonable time (1-2 weeks?).
Highly recommend over the filters that SAY they remove chlorine but don't say how much and don't have research behind them.
