VH410 VIQUA UV Water Disinfection System

VH410 VIQUA UV Water Disinfection System – 2019 Review

The VIQUA VH410 UltraViolet Water Disinfection System neutralizes and kills harmful waterborne microbes.

It’s the best water filter if you suspect that the water coming into your home contains bacteria and cysts such as Giardia, Salmonella and E. Coli.

Standard sediment and activated carbon water filters only remove large particles and certain chemicals from water. Microorganisms go right through these filters.

But most do not survive exposure to UV radiation. The VH410 filter neutralizes the microbes by targeting their DNA, which either disables their ability to reproduce or kills them.  

You can install the VH410 on its own or as part of a whole house filtration system. It’s easy to install and takes up very little space thanks to its compact design.

If you are looking for a sediment or carbon whole house filter to remove chlorine and other impurities, see our top recommendations in this in-depth whole house water filter buying guide.

Pros

  • Protects your family harmful waterborne microorganisms.
  • Easy to install and maintain.
  • Space-efficient design that doesn’t compromise performance.
  • High flow rate.

Cons

  • Doesn't remove any other impurities from water. That's why we recommend using it in concert with other filters.

Water Filter Performance

VH410 VIQUA

UV water filtration is one of the most effective ways of neutralizing illness-causing microorganisms.

Even if you get city water that has already been disinfected using chlorine, you could still benefit from a UV filter.

The VH410 targets chlorine-resistant bacteria such as Sphingomonas TS001, Giardia and Cryptosporidium.

If you receive well water, there's an even greater need to install a UV filter. There are high chances that your water contains a variety of harmful microbes.

If you want to check whether the VH410 UV filter really works, send your water to the lab after installing it. They'll test for the presence of common microbes.

You can also test the water before you install the filter and compare it to the treated water.

Some customers had their water tested, and they got a clean bill of health.

How UV Disinfection Works 

The Viqua VH410 produces what is known as germicidal UV. This consists of short UV wavelengths that target a microorganism's DNA.

The UV radiation causes the bacteria DNA to mutate such that the microorganism cannot reproduce or it dies. In other cases, UV breaks down the DNA bonds, instantly killing or disabling the microorganism

Consistently High UV Output 

For UV disinfection to be effective, it is important that the bacteria be exposed to a high dose of UV radiation for a certain length of time.

The VH410 UV filter provides a consistently high output of UV radiation even during power fluctuations.


Installation & Maintenance  

VH410 VIQUA UV Water Disinfection System review

The VH410 is designed for easy DIY installation. Unless you a very busy schedule, there is no need to hire a plumber.

Remember these points before you start the installation procedure:

  • You can in​​​​stall the filter horizontally or vertically. But vertical installation is the best with the lamp located at the top. This reduces the risk of water damage to the lamp.
  • Make sure the outlet port is located at the top. This ensures there is no air trapped in the UV chamber. 
  • Do not install the filter outdoors. It is rated for indoor use only.
  • Install a 5-micron sediment filter before the VH410. Sediment can reduce the lamp's performance by blocking UV radiation. If you already have a whole house filter system in place, install the VH410 as the last in line.
  • Install the UV system on the main cold water line before it branches off.
  • Remember to leave enough clearance space at the top to remove the UV lamp.

The package includes the UV lamp, the filter housing, and a bracket to secure it to the wall. But you'll have to buy threaded fittings yourself to connect your plumbing to the inlet and outlet ports.

The ports accept both 1” and 3/4" MNPT connectors. 1” is for the outer threading and 3/4" is for the inner threading.

Once you install the filter, open the water supply and check for leaks.

Maintenance 

Note: Remember to switch off water and power before doing any maintenance on the system.

The VH410 UV filter system doesn’t require much in terms of maintenance.

After every few months (about 3), you need to remove and clean the quartz sleeve. This is especially important if you receive hard water, which gradually accumulates scale on the sleeve.

When the quartz sleeve is dirty, it reduces the effectiveness of water purification.

Check the manual for complete instructions on how to remove and clean or replace the quartz sleeve.

To increase the lifespan of the entire system, consider installing a water softener in addition to a water filter.

The bulb also needs to be replaced after about a year or 9,000 hours of operation.

Replacing the lamp takes just a few minutes. Make sure you buy a genuine VH410 replacement bulb.

In case you forget when you are supposed to replace the bulb, there is a handy countdown timer on the digital display.

An alarm will go off once the bulb reaches the end of its lifespan. You’ll also get an alert if the bulb fails for some reason.

 This ensures you are not drinking untreated water without knowing.  

What We Like The Most About The Viqua VH410 UV Water Disinfection System

VH410 UV system

We love the easy setup process. Unlike most whole house water filters that take 3-5 hours to install, it only takes 1-2 hours to set up the VH410.

The compact size definitely helps make installation less tedious.

We are also big fans of low-maintenance systems that don't require calling a plumber every time you need to replace something.

The VH410 filter is a breeze to maintain. Just clean the sleeve every three months and replace the bulb every year, both of which are easy to do.

Something else we love is the high flow rate. At 18 gallons per minutes, you'll not notice any drop in pressure from your shower or faucets.


What We Don't Like About The Viqua VH410 UV Water Disinfection System

Viqua VH410 UV Water Disinfection System

It is positioned as a high-end product, despite the fact that it is a single-stage water filtration system. It costs about the same as large 2 and 3-stage whole house filters.

When you add the cost of yearly replacement bulbs, the overall cost goes up even further.

But it's worth it.

The VH410 gives you peace of mind knowing that your water is safe from disease-causing microbes.


The Viqua VH410 Is Perfect For You If...

VH410 VIQUA UV Water Disinfection System review
  • You are concerned about harmful bacteria and viruses in your water.
  • You already have a whole house sediment and carbon filter. Now you want to add a UV filter to kill bacteria and other microorganisms
  • You want an alternative to under-sink reverse osmosis filter.

Avoid Buying This One If…

VH410 VIQUA UV Water Disinfection
  • You don't already have a sediment whole house filter in place. The UV filter won't work well if your water contains too much sediment. The manufacturer recommends a 5-micron sediment filter.
  • You are looking to remove chlorine, heavy metals and chemicals from your water. The VH410 only targets harmful microorganisms, not chemicals and dissolved substances.

Our Bottom Line

VH410 VIQUA

Reverse Osmosis systems are the best for removing bacteria and viruses from water. But they are expensive, and you can only install an RO filter for one faucet only.

That's not to mention how much they slow down water flow.

A whole house UV filter is a cheaper and more convenient alternative for the entire house. You can effectively disinfect your water at the point of entry without slowing it down.

Even if you already have a whole house water filtration system, I highly recommend you add the VH410 UV filter.

It will provide complete protection to keep your family safe and healthy.
