Water Filter Q&A

Why should I consider a water filter for my home?

Most municipal and well water contains more than just H₂O — trace amounts of chlorine, heavy metals, PFAS (“forever chemicals”), and microplastics can make their way into your tap. A water filter helps reduce these contaminants, improves taste and odor, and gives peace of mind about what you and your family are drinking and bathing in.

Do I need a different filter if I have well water?

Yes. Well water can have a different profile than municipal water — often higher in minerals, bacteria, or sediment. The best approach is to get your well water tested (many companies and local health departments offer testing kits). Once you know what’s in your water, you can choose a filter that addresses those specific issues — like one designed for iron, sulfur, or bacteria.

What types of filters are available?

• Pitcher Filters – simple, affordable, and good for improving taste.

• Countertop Filters – easy to install, no plumbing required.

• Under-Sink Systems – high-capacity, great for families who cook often.

• Whole House Filters – filter water for every faucet and appliance in the home.

• Shower Filters – reduce chlorine, VOCs, and other chemicals that can dry skin and hair.

• Bath Filters – designed for children’s baths and sensitive skin, helping reduce chlorine exposure in bathwater.

Brand Spotlights

Here are a few well-known water filter brands and what they’re known for:

• Aquasana – Offers whole-house, shower, and under-sink systems; strong focus on reducing chlorine, PFAS, lead, and pesticides. NSF/ANSI certified.

• Culligan – A long-standing water company offering whole-house systems, softeners, drinking water filters, and shower filters with professional installation.

• AquaTru – Specializes in countertop reverse osmosis systems; removes fluoride, lead, PFAS, and other contaminants without requiring plumbing. NSF certified.

• WaterChef – Known for under-sink, countertop, and shower systems with long filter lifespans; uses block carbon technology to target chlorine, lead, and VOCs.

How often do filters need to be replaced?

It depends on the brand and filter type. Pitcher and countertop filters may need replacement every 3–6 months, while under-sink, shower, and whole-house filters can last 6–12 months or longer. Always check your brand’s guidelines — a clogged filter won’t work effectively.

Does filtering water remove healthy minerals?

Carbon block and whole-house filters typically leave beneficial minerals (like calcium and magnesium) intact. Reverse osmosis systems remove most minerals, but you can remineralize with drops or by using a filter that adds minerals back in.
