Best Filters for Chlorine Removal

Chlorine in tap water is very common, since chlorination of municipal water supplies is a widespread and popular method to disinfect water with the purpose of eradicating disease-causing bacteria, viruses and cysts from tap water. Luckily, chlorine is fairly easy to remove from water with the help of carbon based chlorine removal filters.

Chlorine has a strong odour and can be tasted when drinking water straight out of the tap. Chlorine levels in water should not exceed 4 mg/l, which is deemed safe for human consumption. However, even levels much lower than 4 mg/l can cause issues to some immunocompromised individuals, or persons suffering from asthma or skin conditions.

Whether you’re an at-risk category or you’re worried about the long-term effects of chlorine exposure, we’ve gathered the best filters to remove chlorine from water.

Health Impact of Chlorine in Tap Water

Chlorine is one of the most inexpensive ways to protects against water-borne diseases. Sometimes, chlorine is combined with other disinfectants like chloramine, which is formed by adding ammonia to water that contains free chlorine.

Whichever chemical disinfectant is used, by-products (e.g. trihalomethanes, haloacetic acids) may form when these chemicals enter into contact with other water ingredients. Both chemical disinfectant by-products and chemical disinfectants have side-effects that should not be taken lightly, especially by at-risk categories.

Some of the most notable side-effects of chlorine and their by-products include:

  • Dry hair and skin, skin rashes, itchiness, psoriasis and eczema flare-ups when bathing in chlorinated water;
  • Asthma attacks if inhaled when showering or bathing;
  • Chlorine by-products are considered cancerogenic, leading to an increased risk of breast cancer and bladder cancer;
  • Nervous system effects in infants and small children;
  • Reproductive problems and miscarriage.

Tap water treated with chlorine has a bleach-like taste and odour, which is also an issue from those wanting to switch from bottled water to tap, but simply can’t stand the taste or odour of chlorinated tap water. Luckily, chlorine removal filters do a great job at removing taste and odour issues as well.

How to Remove Chlorine from Tap Water?

Whether you’re worried about the harmful health effects of long-time chlorine exposure or you’re an at-risk category, there are various types of filters you can use to remove chlorine from tap water.

Before we delve into the different chlorine removal filters, chlorine can be removed from water through aeration as well, i.e., letting water “breathe” on the sun, for example. While this is a simple method, letting water out on the sun will certainly affect its freshness, so it’s mainly recommended if you want to water your plants with chlorine-free water.

Apart from aeration, here are the fastest and best methods to remove chlorine from tap water:

  • Activated carbon filters: made from raw organic materials like coconut shell or wood, activated carbon filters are one of the best ways to remove chlorine, its by-products, and solve taste and odour issues related to chlorine. Available in two forms – carbon block and granular activated carbon – these filters can remove up to 99.9% of chlorine from tap water.
  • Ceramic filters: ceramic filters are another filter media that can remove chlorine from water, especially if combined with carbon filters.
  • Multi-stage reverse osmosis filters: multi-stage reverse osmosis filters have both carbon block and granular activated pre- and post-filters, ensuring chlorine-free and odourless tap water.

Wrap-up

Even at recommended safe levels, exposure to chlorine can be dangerous to some at-risk categories (those suffering from asthma, skin conditions, pregnant women, infants, etc.). Long-term exposure to chlorine is not without its risks either.

Water filters designed to remove chlorine, disinfectant by-products, and improve the taste and odour of tap water are the best way to protect yourself from the unwanted effects of chlorination.
