Frizzlife PX500-A Overview

Frizzlife PX500-A

The Frizzlife PX500-A is a tankless under sink RO water filtration system with a high daily output of 500 gallons. It filters water in 7 stages, including an alkaline remineralization stage.

It has a filtered to waste water ratio of 1.5:1

The system filters more than 1000 contaminants from water, including chloramine, TDS, lead and other heavy metals.

The PX500-A measures 14 x 5 x 18 inches and weighs 23.7 pounds. It’s also space-saving and will fit your tiny under sink space quite well.

Design: The Frizzlife PX500-A comes in a tankless design, a feature that makes it take less space under the counter. It also swipes out secondary contamination caused by an unventilated tank.

Access to changeable filters is readily available on the unit’s front side, making filter replacements fast and simple.

Filtration Performance: This system adopts a composite pre-filter, post alkaline filter and a high-grade RO membrane with 0.0001-micron filtration capacity.

As aforementioned, this system filters water in 7 stages. In the 1st stage, a pleated 3-in-1 filter (ASR311) blocks debris and reduces particles like silt, sand, rust and insoluble impurities from the water.

This filter not only conditions the water but also prolongs the life of the RO membrane.

In stage 2, a high-grade 0.0001-micron reverse osmosis membrane(ASR313-500G)  eliminates 99% of 1000+ contaminants, including lead, chlorine, fluoride, chloramines, VOCs, heavy metals, among others.

Enter stage 3…

Here, a post alkaline and remineralization filter alkalizes the water pH level by reintroducing essential minerals into the water.

The post-filter utilizes the natural elemental tiny stones and particles to restore essential minerals and alkalize the water pH to above 7.5.

Water Flow Rate: The PX500-A has a fast water flow rate and produces 500 gallons of pure water per day. With this high capacity, the unit can serve any big family comfortably.

In fact, it can fill a cup of fresh water within 12 seconds. It’s that fast!

The unit is highly efficient, with a pure to waste water ratio of 1.5:1, meaning that for every 1.5 gallons of pure water produced, only one gallon of water goes to waste.

It’s, therefore, true to say that the PX500-A makes water bills more affordable, is water-saving and inexpensive in the long run.

Filter Life Monitor: To remind you to change the filters in advance, the system has a color-coded monitor embedded in the operation panel. Blue indicates that it’s all good, while red indicates that you need to change the filters.

It’s recommended that you change the pre-filter (ASR311) every 6 months and the post-filter (ASR313-A) every 12 months. The reverse osmosis membrane requires changing every 2 years.

Installation and Maintenance: The installation of the Frizzlife PX500-A is very simple and straightforward. With basic DIY skills, you can install it in an hour.

Everything required for installation comes with the package, including a brush nickel faucet. It also comes with a detailed manual to help go about the process.

The system is equally easy to maintain thanks to the filter life indicator feature. The indicator blinks red when the filter’s remaining time is less than 5%.

The light stays red, and you will hear a loud buzzer

if it gets too low (0%).

Power off the system and turn on the RO faucet to drain the water to replace the filter. When this is done, remove the system’s faceplate and twist out the old filter.

Next, twist in the new filter and turn the power back on.

Finally, reset the filter as indicated in the manual.

Pros

  • High water flow rate
  • Compact and space-saving
  • 1.5:1 low drain ratio
  • Removes 1000+ water contaminants
  • Superior water filtration technology
  • DIY installation and easy filter change
  • Has a filter life indicator
  • Comes with a remineralization and alkaline filter

Cons

  • A little noisy when processing water
  • Filters can be a little hard to twist in and out

Aquasana OptimH20 RO System AQ-RO-3 Overview

Aquasana OptimH20 RO System AQ-RO-3

The Aquasana AQ-RO-3 is a water filtration system that removes 5 times more contaminants than other RO systems as it combines 3 technologies to purify the water.

It uses reverse osmosis, advanced Claryum filtration and remineralization to filter and reinstate the lost minerals back into your water.

The system removes up to 97% chlorine, 95% fluoride and 99% of 88 other contaminants.

Unlike the Frizzlife PX500-A, which is tankless, this system comes with a storage tank that stores your pure water awaiting use.

The system produces 36 gallons of water per day, measures 30 x 50 x 12.5 inches, weighs 12.3 pounds and is NSF certified to remove lead, mercury, chromium, chlorine, asbestos, arsenic, chloramine and fluoride.

Filtration Process: The AQ-RO-3 filters water in 3 stages to provide you with clean, pure and healthy water for drinking and other domestic uses.

So how does the system work?

In stage one, the reverse osmosis membrane gets rid of most contaminants, including TDS, arsenic, fluoride, nitrates, and bacteria.

The 2nd stage (Claryum filter) consists of 3 stages, i.e., catalytic carbon, ion-exchange filtration and sub-micron mechanical filtration.

The catalytic carbon eliminates common disinfectants like chlorine and chloramines.

Heavy metals like lead, mercury, iron and heavy ions are removed in the ion-exchange stage. Substances like Cryptosporidium and Giardia are removed through sub-micron mechanical filtration.

And finally, in the 3rd stage, the remineralization filter reintroduces essential minerals like potassium, calcium and magnesium into the water, making it tastier and healthier.

Water Flow Rate: This system produces up to 36 gallons of ultra-pure water per day. Although this is much lower compared to models with a daily output of more than 100 gallons, the system is still efficient enough for small families.

Designer faucet: The AQ-RO-3 comes with a stylish designer faucet that’s 100% lead-free. The faucet is pretty easy to install and comes in a variety of finishes for you to choose from.

Installation and Maintenance: Although easy to install, you can still face some difficulties installing the system’s outlet faucet if your work surface does not have an existing hole.

With most RO systems, only a ½ or 3/8-inch diameter hole is required for the faucet. However, the AQ-RO-3 comes with an air gap faucet that requires a hole with a 1 ½ to 1 5/8 inch diameter.

Drilling a hole that size is a complicated process, and you’ll thus require the help of a plumber.

On the other hand, the installation process will be very easy if there’s a suitable hole for the faucet on your sink or work surface. All you need to do is follow the step-by-step instructions in the manual to set the unit up.

Maintaining the system is also a breeze since the filters are extremely easy to remove and replace. The reverse osmosis can last up to 3 years; the Claryum filter lasts for about 6 months, and the remineralizing filter for 12 months.

Warranty: This Aquasana RO system comes with a 90-day satisfaction guarantee that enables you to return it for a full refund if unsatisfied with its performance (only 90 days since the day of purchase).

It is also supported by a two-year limited warranty
