Effective Water Filters to Remove Pseudomonas: A Complete Guide

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.

Pseudomonas can be spread to hospital patients and those in the healthcare system. It's transmitted when someone is exposed to water or soil contaminated with these germs. In water, pseudomonas causes a funny taste and smell, and it creates a 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.

Which Water Filters Effectively Remove Pseudomonas?

Water filters with a pore-size smaller than 0.5 micron can remove pseudomonas. Pseudomonas are rod-shaped bacteria 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 it with boiling water between each use to protect yourself from pseudomonas.

Ultrafiltration: An Excellent Solution for Removing Pseudomonas, Bacteria, and Viruses

PS-1000 Whole House Ultrafiltration System with 0.02 Micron Membrane

The best whole house water filter for bacteria and viruses is the PS-1000 ultrafiltration membrane filter. For homes with lead, sediment, or chemicals in the water, consider 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.

Key features of the PS-1000:

• Ultrafiltration technology does not require a storage tank or electricity to operate
• Easily cleanable membrane: simply turn a valve to flush it
• Membrane lasts 3 – 5 years (or more), saving money in the long-run
• No drop in water quality over time
• Flush the 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: It 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 Ultrafiltration Drinking Water System with 0.02 Micron Membrane

The PS-PURUF is great for removing bacteria and viruses, and delivers water on demand – no storage tank required. This means no bacteria growth (tanks are notorious for bacteria growth) and it requires significantly less space under your sink.

Key features of the PS-PURUF:

• Back flushing membrane ensures longer water membrane life
• Innovative technology lets you flush (clean) the membrane whenever it gets full of contaminants
• Membrane should be replaced every 2-3 years
• High capacity coconut shell carbon block cartridges remove lead, parasites, cloudiness, sediment, offensive taste/odor, chlorine, chloramine, THMs, VOCs, 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.

Submicron Filters: A Reliable Defense Against Pseudomonas, Bacteria, and Viruses

PS-1HFC High Flow Under Sink Water Filter System with 0.2 Micron Filtration

The PS-1HFC is excellent for providing pharmaceutical-grade filtration at a high flow rate, working with your existing faucet. This system offers advanced filtration without the need for a separate faucet or storage tank, saving space under your sink and eliminating the risk of bacteria growth associated with storage tanks.

Key features of the PS-1HFC:

• Exceptional 0.2 micron filtration removes a wide range of contaminants
• Long-lasting filter cartridge with 2-year / 10,000 gallon lifespan
• Easy installation directly to existing kitchen or bathroom faucets
• Compact design ideal for limited spaces and renters
• No need for electricity or a separate faucet
• Quick, easy, and sanitary filter replacement

The PS-1HFC effectively reduces or eliminates:

• Chlorine, chloramine, and other chemicals
• Lead and heavy metals
• Bacteria, parasitic cysts, and cryptosporidium
• VOCs, THMs, and MTBE
• Sediment, dirt, and cloudiness
• Asbestos, mold, and algae spores
• Oxidized iron, manganese, and sulfides
• Pharmaceuticals and emerging contaminants
• Limescale and scale build-up in appliances

Why the PS-1HFC is one of the best high-flow water filters and worth buying: It offers pharmaceutical-grade filtration at a high flow rate, with an impressive 2-year filter life. This system provides advanced filtration without the need for a separate faucet or storage tank, making it perfect for those who want clean water with minimal fuss and maximum efficiency.

BG-202BIV Two Stage Whole House Bacteria Water Filtration System with Scale Inhibitor

The Premiere BG-202BIV is a two stage whole house water filter with a "charged" nanofiber cartridge and a 5 micron activated carbon block cartridge with scale control.

This system removes:

• Bacteria, cryptosporidium, giardia, parasites, endotoxins
• Sediment, cloudiness, DNA
• Iron, manganese
• Chlorine taste and odor
• Trihalomethanes (THMs), methyl tertiary butyl ether (MTBE), volatile organic chemicals (VOCs)

Compared to the ultrafiltration systems discussed above, the BG-202BIV is 0.5 micron (ultrafiltration purifies to 0.02 micron) 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 -Single-Stage Whole House Submicron Water Filter System

The BG-10BIV and BG-20BIV systems each contain a 0.5 micron absolute rating "charged" nanofiber cartridge that removes bacteria, parasites, fine particulates, and other contaminants as small as 0.5 micron.

Key features:

• Absolute "charged" nanofiber filter with high Zeta potential for effective reduction of ultrafine contaminants
• Whole house / point of entry filter for homes or apartments requiring 10 GPM or 20 GPM flow rate or less

UV, Ozone, and Reverse Osmosis: Alternative Methods to Remove Pseudomonas, Bacteria, and Viruses

Ultraviolet (UV) or ozone purification

Kills pseudomonas and bacteria, but it doesn't remove bacteria from the water. 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:

• Membranes can have defects which allow bacteria to pass through
• Bacteria may move around the o-ring seals in reverse osmosis systems
• Bacteria can potentially move up the pure water stream and attach to the RO membrane

HydroGuard HGDT-45 Reverse Osmosis System

The Hydro Guard HDGT-45 series reverse osmosis system reduces the levels of lead, nitrates, cysts (cryptosporidium, giardia), arsenic, sodium and other contaminants commonly found in tap water.

Key features:

• Easy to install
• Uses sanitary quick change filters for fast, convenient, and sanitary filter changes
• Leak detector shut off valve (FLOWLOK ™) which silently guards against any water leaks
• Compact design
• Delivers quality water from your tap on demand

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