A Guide to Algae in Drinking Water: How to Get Rid of Algae in Drinking Water + How to Prevent Green Algae Bacteria in Filtered Water Pitchers

There are many different types of algae and depending on the type, it could have a positive, neutral, or negative effect on water. For this article though, we’ll be focusing on the particularly nasty (and dangerous!) types of algae that can wind up in drinking water.

Water Filters to Remove Algae in Drinking Water

As lakes and rivers warm, reports of harmful algal blooms are on the rise. These algal blooms affect recreational activities such as lakes being closed for swimming, fishing, etc.. If pets play in or drink water with toxic algae it can be lethal; sadly last summer it made national headlines when three dogs died in North Carolina after  swimming in a pond that had toxic algae. Algae blooms can also affect drinking water supplies.

Toxic algae blooms are most common in the summer when the weather is warm and waters are stagnant. Unfortunately, it’s not unheard of for water districts to advise residents to not drink the tap water because of a harmful outbreak. Hopefully when an outbreak does occur that water district implements systems and protocols so that it doesn’t happen again, but there’s no guarantees.

Even if the algae in drinking water is not deemed as harmful, it can impact the taste and odor of drinking water. For example, earlier this month residents of Fayettville, Arkansas were advised that their tap water tastes and smells differently due to increased amounts of algae in Beaver Lake (officials say the water is still safe to drink). The algae gives a “fishy” taste and smell to water.

I don’t know about you, but I certainly don’t fancy drinking water that’s been contaminated by algae, even the harmless kind.

The best course of action to avoid algae in drinking water is with a water filtration system. Not only will it protect you against harmful algae but a whole range of contaminants too.

Best Drinking Water Filters to Remove Algae

Most reasonable and it’s portable: MP-CT Countertop Water Filter System, 2,000 Gallon Filter Life

The MP-CT countertop water filter system contains a 0.5 micron water filter that protects you from algae and other contaminants including lead, chlorine, cysts, mold, THMs, VOCs, and more. Enjoy 2,000 gallons of clean, great-tasting drinking water. Space-saving design and easy installation. It’s portable too – bring it wherever you go that has a standard faucet.

Best all-round for price: EC-700 Under Sink Water Filter System, 2,500 Gallon Filter Life

The EC-700 under sink water filter system removes contaminants 0.5 micron and larger including chlorine, chloramine, cysts (including cryptosporidium and giardia), lead, mold, MTBE (methyl tertiary butyl ether), oxidized iron / manganese / sulfides, offensive taste and odor, sediment / dirt / cloudiness, THMs (trihalomethanes), VOCs (volatile organic chemicals), and more. It absorbs offensive tastes and odors including common earthy, moldy, or fishy ones. It retains vital minerals found naturally in water. The EC-700 is easily installed and provides crisp, clean drinking water. Extremely long cartridge life of 2,500 gallons and excellent flow rate of 1.75 gallons per minute.

Latest & greatest technology: PS-PURUF Ultrafiltration Under Sink Membrane Purification System

Ultrafiltration is a type of membrane filtration which purifies and disinfects water. A membrane barrier acts like a filter using slight pressure to separate particles like bacteria, viruses, germs, pollen, algae, and organic molecules from the water. The PS-PURUF has patented 0.02 submicron membrane which removes over 99.9% of contaminants, bacteria, cysts, viruses, giardia, and cryptosporidium. Innovative technology lets you flush (clean) the membrane whenever it gets full of contaminants. No storage tank required means no bacteria growth and significantly less space required.

How to Avoid Green Algae And Bacteria Contamination In Your Filtered Water Pitcher (Brita, PUR, ZeroWater pitcher filters)

PS-SQC50 Hydro Guard reverse osmosis system Premiere countertop water filter systemConsider switching to an under sink water filter or countertop water filter.  Even though an under sink water filtration may seem more expensive, the better filtration is totally worth it! Not to mention, you’ll save the time and expense of replacing filters as often. It might also surprise you that a high quality countertop water filters that easily attaches to your faucet are only $99.

Pitcher filters may claim to reduce up to 99% of contaminants but in reality they are limited by what they can filter due to the filter media and micron rating. For example, Brita, PUR, and ZeroWater pitcher filters do remove bacteria or viruses.  An appropriate under sink water filter does a much better job of filtering out dissolved solids, bacteria, chemicals, and more. This means no more green algae, mold, floating black specks (charcoal particles), sediment, stains, or other bacterial buildup in your pitcher or the filters themselves.

Ensure a tight seal on top of your filtered water pitcher. The lid and spout form a tight seal with the rest of the pitcher when closed. A tight seal stops air, dust, food particles, and contaminants from getting in. If your pitcher doesn’t have a tight seal you might as well recycle it and get a new water filtration solution.

Wash your filter pitcher often and thoroughly. This one seems like a no-brainer but folks often forget to do so. Wash your filter pitcher out once a month at the very least. Wash it thoroughly with dish soap or run it through the dishwasher for even better results. Although it may take week or months for bacteria to accumulate to a level where it’s visibly nasty, washing it consistently will help with the bacteria you can’t see.

Replace the water filter often. Be sure to change your filter as often or more than the recommended amount.  When filters get clogged with sediment and other particles then they can become breeding grounds for bacteria and algae, which will reduce the filtering abilities even further. When your filter sensor light gets to yellow it’s time to swap in a new one. This will unfortunately end up costing you a few extra dollars but it’s worth it and if you buy the filters in bulk you’ll be fine.

Wash your hands and the replacement water filter before using it. Before you replace the filter in your pitcher, wash your hands thoroughly with anti-bacterial hand soap. While you’re at it, carefully wash the plastic exterior of the Brita filter too. Or, wipe down the outside of the Brita filter with an antibacterial wipe. Then proceed to rinse each Brita filter under cold water for the recommended time before putting it in the pitcher.

Keep your water filter pitcher in the fridge. Keeping the water cold helps reduce and prevent bacterial or algae buildup.

Don’t drink directly from the water filter pitcher. It’s nasty, just don’t do it.

Follow the instructions – dump the first 1-2 pitcher fillers after you replace your filter. Avoid charcoal dust contamination by running a couple fills through your pitcher and dumping them after you change the filter in your pitcher. Even though Brita and other manufacturers claim these black charcoal specks are harmless, it’s just not healthy to drink them.
