What is pseudomonas?

Pseudomonas is a type of bacteria that's relatively common in water and soil. Pseudomonas aeruginosa is the most widely known; it causes the highest number of infections in humans. It can be be spread to hospital patients and those in the healthcare system. Pseudomonas is spread when someone is exposed to water or soil contaminated with these germs. Pseudomonas cause a funny taste and smell in water, and distinctively sour smell in damp dishcloths.

Can pseudomonas be in water?

Yes, pseudomonas are common in the environment including water. If your drinking water has an earthy or musty smell and/or strange and earthy taste, you may have Pseudomonas in your water. Although Pseudomonas is bacteria, you could come into contact with pseudomonas and not get sick if you're healthy. However, if your immune system is compromised, pseudomonas can cause serious infection.

What water filters remove pseudomonas?

Water filters with a pore-size smaller than 0.5 micron can remove pseudomonas. Pseudomonas are a rod-shaped bacterium measuring 0.5 to 0.8 μm by 1.5 to 3.0 μm and therefore require a submicron filter to remove them. Keep in mind that pseudomonas can live on dispensing devices, carbon filters, water taps, water bottles, and even in bottled water itself, so a water filter is only as good as where / how the water is being consumed. If you have a reusable water bottle, sterilize your water bottles with boiling water between each use to protect yourself from pseudomonas.

Ultrafiltration removes pseudomonas and other bacteria and viruses

PS-1000 Whole House ultrafiltration membrane filter system (0.02 submicron)

The best whole house water filter for bacteria and viruses is the PS-1000 ultrafiltration membrane filter. Or, if you have lead or lots of sediment or chemicals in the water, the PS-2000PB, PS-2000S or PS-2000C respectively. The Premiere PS-1000 ultrafiltration systems removes bacteria (over 99.9999%), viruses (over 99.99%), and giardia & cryptosporidium (over 99.95%) from your water. It has a continuous, 8 gallon per minute flow rate (dependent on water pressure) which is suitable for most homes. If you need a higher flow rate, you can “stack” these systems. Ultrafiltration technology does not require a storage tank or electricity to operate. One of the best features of this ultrafiltration system is that you can easily clean the membrane: simply turn a valve to flush it. This cleanable membrane saves money in the long-run because it lasts 3 – 5 years (or more). There’s also no drop in water quality. With other filter systems, there’s no option to turn a valve to clean the filter – it means you have to buy a new replacement water filter. Don’t waste time and money changing filters every year, six months, or more with other filter systems. You’ll know it’s time to flush the PS-1000 membrane when there is a drop in water pressure coming from the system.

Why the PS-1000 is one of the best water filters for pseudomonas and worth buying: Has an easy to flush membrane filter that lasts 3 – 5 years. Other technology which removes ultrafine contaminants can’t compete with this filter life. In the long-run, you’ll save money by not having to replace filters as often, whilst benefiting from the outstanding bacteria removal.

PS-PURUF Drinking Water ultrafiltration system (0.02 submicron)

The PS-PURUF is great for removing bacteria and viruses, and delivers water on demand – no storage tank required. No storage tank means that there is no bacteria growth (tanks are notorious for bacteria growth) and also requires significantly less space under your sink. Back flushing membrane ensures longer water membrane life. When a membrane undergoes a backward flush, its pores are flushed inside out to get rid of the contaminants it has captured. Innovative technology lets you flush (clean) the membrane whenever it gets full of contaminants. Simply turn the valve to flush the membrane (please note that a small amount of water will be discharged while the valve is open). The membrane should be replaced every 2-3 years. High capacity coconut shell carbon block cartridges also removes lead, parasites (cryptosporidium & giardia), cloudiness (turbidity), sediment, offensive taste/odor, chlorine, chloramine, THMs (trihalomethanes), VOCs (volatile organic chemicals), asbestos, and more.

Why the PS-PURUF is one of the best bacteria water filters and worth buying: It’s a reasonably priced under sink water filter that removes bacteria, viruses, cysts and chemicals with zero waste water in the production of pure water (unlike reverse osmosis), and you can flush the membrane when it gets full of contaminants. 

Absolute charged nanofiber filters removes pseudomonas and other bacteria and viruses.

BG-202BIV – Two Stage Point of Entry Water Filtration System

The Premiere BG-202BIV is a two stage whole house water filter with a “charged” nanofiber cartridge and a 5 micron coconut shell activated carbon block cartridge. This system removes bacteria, cryptosporidium, giardia, parasites, endotoxins, sediment, cloudiness, DNA, iron, manganese, chlorine, taste, odor, chlorine, chloramine, trihalomethanes (THMs), methyl tertiary butyl ether (MTBE), volatile organic chemicals (VOCs), and more. The carbon block filter cartridge also has scale inhibitor for hard water. Compared to the ultrafiltration systems discussed above, the BG-202BIV is 0.2 micron (ultrafiltration purifies to 0.02 micron – note the extra zero!) and the filters need to be changed, not flushed.

Why the BG-202BIV is one of the best bacteria water filters and worth buying: It’s a reasonably priced whole house water filter that removes bacteria, viruses, cysts and chemicals.

BG-10BIV or BG-20BIV - Submicron Point of Entry Water Filter System (10 or 20 gallon per minute flow rate) The BG-10BIV and BG-20BIV systems each contain a 0.2 micron absolute rating “charged” nanofiber cartridge that removes bacteria, parasites, ultrafine particulates, and other contaminants as small as 0.2 micron. The absolute “charged” nanofiber filter has a high Zeta potential for effective reduction of ultrafine contaminants. It's a whole house / point of entry filter for homes or apartments requiring 10 GPM or 20 GPM flow rate or less.  

Other technology for removing pseudonomas in water:

• Ultraviolet (UV) or ozone purification kills pseudomonas and bacteria, but it doesn’t remove bacteria from the water. That means that bacterial remnants are still present in your water. Plus, it requires a lot of electricity.
• Reverse osmosis can remove pseudomonas and bacteria, but some systems are imperfect. As a process reverse osmosis does remove bacteria since it can’t pass through the reverse osmosis membrane due to size. However, membranes can have defects which allow the bacteria to pass through. Sometimes bacteria will even move around the o-ring seals in reverse osmosis systems. There’s also the possibility that bacteria can move up the pure water stream and attach to the RO membrane.

HydroGuard HGDT-45 Reverse Osmosis System

Enjoy clean, safe drinking water with the Hydro Guard HDGT-45 series reverse osmosis system. It reduces the levels of lead, nitrates, cysts (cryptosporidium, giardia), arsenic, sodium and other contaminants commonly found in tap water. This reverse osmosis system is easy to install, and uses sanitary quick change filters which makes changing water filters fast, convenient and sanitary. One of the revolutionary features of this system is its leak detector shut off valve (FLOWLOK ™) which silently guards against any water leaks which may occur. The Hydro Guard HDGT-45 features a compact design and delivers quality water from your tap whenever you want it.

Why the HDGT-45 is a great system for removing bacteria and worth buying: Reverse osmosis has a pore size of 0.0001 micron so eliminates virtually everything in water including bacteria. It's a high quality and affordable system for drinking water.
