A new bathtub filter from Canopy is drawing attention from people concerned about contaminants in tap water. The product, priced at $89, aims to remove chlorine, heavy metals, and some PFAs, also known as “forever chemicals,” from bathwater.
The filter uses a three-step system. Activated carbon attracts and traps contaminants through microscopic pores. Calcium sulfite reacts with chlorine and chloramines, neutralizing 99% of chlorine in the water. KDF-55, a copper-zinc alloy, uses a chemical reaction to trap heavy metals and stop microbial growth.
Water enters through a BPA-free silicone spout and passes through the filter before entering the tub. The company says the filter can remove some PFAs, depending on water pressure and the specific compound.
Installation takes less than 20 seconds and does not require tools. Each kit includes two stretchy silicone bands. Users choose the band that fits their spout, slip it on, and attach the filter. The filter has small grips that fit into the band’s grooves to prevent leaking.
The filter comes in five colors: white, butter, jade, lavender, and oat. The company chose muted versions of each color. The design aims to appeal to both adults and children.
Users report that the filter does not affect water pressure. One reviewer said it took about three minutes to fill a tub, the same as without a filter.
The filter includes a small water temperature indicator on the side. It changes from gray to red when the water is hot. This helps users avoid drawing a bath that is too hot.
Maintenance is simple. The silicone spout cover is dishwasher-safe. It has built-in ventilation and an antimicrobial coating to resist mold and mildew. The water filter must be replaced every 90 days. It can be replaced without removing the spout cover.
Some users note that the spout cover is large. The company designed it to fit a variety of spout sizes and shapes. A slimmer profile would be preferred by some, but the larger size allows for versatility.
The product is made with silicone. Early research suggests silicone may release nanoplastic over time or under harsh conditions. Silicone is also a synthetic polymer that is difficult to recycle. This may lead some people to avoid the product despite its benefits.
Nearly half of U.S. tap water contains PFAs, according to a study published in ScienceDirect. PFAs have been linked to an increased risk of cancer, altered metabolism, and a reduced immune system. Tap water is also treated with disinfectants like chlorine, which can damage the skin barrier, causing dryness, redness, and irritation.
Older buildings may have lead soldering in the piping, exposing residents to heavy metals. Hard water, which has high levels of calcium and magnesium, can also strip the skin. The filter addresses these concerns by removing a range of contaminants.
The Canopy Bath Tub Filter is part of a broader trend of home water filtration products. The company also makes a shower filter and a sink faucet filter. All use the same three-step filtration system. The bathtub filter is the newest addition to the line.
