Disadvantages may include filters that have to be replaced more frequently, less water output per day and a slower flow rate as well as less filtration stages.

APEC RO-CTOP Reverse Osmosis Water Filter System (Installation-Free)

The Good

APEC RO-CTOP Installation-Free Water Filter

In our first countertop reverse osmosis water filter review we take a look at the APEC RO-CTOP system:

APEC (Advanced Purification Engineering Corp.) Water Systems is among the leading manufacturers of residential ro water filter units in the United States. All of the company’s products are NSF compliant, BPA-free and Made in USA. All in all the company looks back at 20+ years of industry experience.

The APEC RO-CTOP can be attached to most standard faucets in under 5 minutes. No installation is required here. Once connected, make sure to let the water rinse the system for about 15 minutes, if you are using it for the first time. Afterwards you can enjoy 99% contaminant-free drinking water with a capacity of up to 90 GPD (at 60 psi water pressure), which is sufficient even for a larger household.

The 4-Stage filtration process removes dust, particles, rust, chlorine, odors, cloudiness, colors and common chemicals, arsenic, lead, fluoride, chromium, radium, bacteria, viruses and more. Pre-stage filters (stage 1 and 2) need to be replaced once every 6-8 months, 3rd and 4th stage filters every 2-3 years. Replacement packs come at a reasonable price.

Tests have shown that the countertop system is able to reduce the TDS by 98.8% from 225ppm to only 3ppm confirming APEC’s claims. More than 160 amazon reviews show that the company is trusted by its customers. View some of the reviews here. (*amazon-link)

The not so Good

Unfortunately the APEC RO-CTOP is relatively expensive (about $230). Some competitor products cost $100 and less. However, bear in mind the 1-year limited warranty which backs up the unit as well as APEC’s excellent customer service.

Bottom Line

If your budget allows, the APEC RO-CTOP is a great choice for everyone who is looking for high quality. In our opinion it’s the best countertop reverse osmosis system out there. The model is placed at the upper end of the price scale, but therefore made and certified in the US and backed by APEC’s highly capable customer support and a 1-year limited warranty.

Reverse Osmosis Revolution Countertop Portable 5-Stage System

The Good

Reverse Osmosis Revolution Countertop Portable 5-Stage System

The number one reason to buy a filtration unit from Reverse Osmosis Revolution is its low price. The US-based company sells some of the cheapest models on the market. Taking this into consideration one would not expect their systems to be of remarkable high quality. And they would be right, but this countertop portable 5-stage unit is still Made in USA and delivers about 3 gallons of filtered water per hour, which adds up to about 75 gallons per day.

Apart from the standard filtration stages which remove dust, rust and other dissolved particles, this system comes with a built-in deionizing filter and a T33 post polishing filter. Both filters are US made and reduce TDS to an exceptional high degree.

EPA tests have shown a removal of 80% to 100% of triazine, 98.5% to 100% of acetanilide, 98.5% to 100% of organophosphorus pesticides, 92.9% or more of carbamate pesticides and a 82% to 92% removal of fluoride. TDS (Total Dissolved Solids) where reduced from 445 parts per million to less than 10 parts per million.

According to the manufacturer the system can be attached to 96% of all kitchen faucets in under 5 minutes without having to drill into your countertop. This is especially nice for renters, who don’t want to make any permanent changes to their apartment. Clear and concise instructions are shipped with the product.

You can get a comprehensive overview over all positive aspects on amazon, if you are still unsure about whether or not this unit is the right choice for you.

The not so Good

The ROR countertop system has received some negative feedback due to customers receiving defective products or products with missing parts.

Furthermore the model is known for water leakages that might occur. If you experience any problems, make sure to reach out and get in touch with the vendor. Support is very responsive and works hard to rectify any issue.

Bottom Line

The bottom line is that ROR offers a decent product that is US made and EPA tested. It’s also cheaper than most of its competitors. The downside is malfunctioning products being shipped every once in a while.

HydroLogic 31026 Micro Countertop Reverse Osmosis Water Filter Review

The Good

Hydrologic 31026 Micro RO Water Filter

HydroLogic Purification Systems specializes in a broad range of professional water purification products. The company looks back at 11+ years of experience, is based in Santa Cruz, California and has all of their systems build in California or Arizona.

The HydroLogic 31026 Micro reverse osmosis system is compact and therefore highly portable, produces up to 75 gallons of water per day, which is sufficient for a family of 4 and can easily be hooked up to a kitchen faucet in no time.

Other features are a surprisingly fast delivery, only 2 gallons of wastewater produced for every gallon of filtered water, which is a real money saver and an integrated and very accurate pressure gauge, which allows you to monitor water pressure.

The not so Good

Instructions could use some work. Another minor disadvantage is that in order to hook up the system to your 3/4″ bathroom faucet, you need another adapter from your local hardware store.

Bottom Line

With the 31026 Micro reverse osmosis water filter unit HydroLogic has designed a solid product that does what it says and comes at a reasonable price. No downsides here!

Purewaterclub POQ-4B-50 Portable RO System

Disclaimer:
The Purewaterclub POQ-4B-50 portable ro system provides filtered water that is also deionized and therefore not safe for human consumption. If you intend to drink the water, we recommend you to opt for a different model or purchase additional filters.

The Good

Purewaterclub POQ-4B-50 Portable RO Unit

Installing the Purewaterclub POQ-4B-50 is simple. Even if you know nothing about plumbing, you should be able to follow the instructions provided. After a few minutes of setup, your system is ready to start working. Turn on the valves and you’ll have pure water.

The 4 filtration stages remove 99% of sodium, aluminum, lead, nitrate, silicate, ammonium, barium, chromium and many more substances plus 99% of all bacteria in the water. In a test conducted in Q4 2014 the countertop system was able to reduce TDS from 80ppm to 1.5ppm on average, showing that the POQ-4B-50 can compete with the big brands.

Depending on the pressure it will take between 15 to 20 minutes to fill one gallon of water.

The not so Good

Purewaterclub reverse osmosis systems are sold by PW TEC CORP which is based in Rowland Heights, CA. But whether or not the POQ-4B-50 portable unit is Made in USA we do not know. PW TEC does not accept phone calls and rarely responds to email enquiries.

Above that you might need to make a trip to the local hardware store to buy a few items you need for system installment as the ones provided are of lower quality, such as a faucet attachment which costs you about $2.

Bottom Line

It’s hard to beat the POQ-4B-50 portable countertop in terms of price-performance-ratio. The processed water can be used to fill your fish tank and much more. A UV-filter would probably make a good addition for added insurance of killing any pathogenic germs that may survive the system.

Purewaterclub POQ-4B-100 RO+DI Filtration Unit

Disclaimer:
The Purewaterclub POQ-4B-100 portable ro system provides filtered water that is also deionized and therefore not safe for human consumption. If you intend to drink the water, we recommend you to opt for a different model or purchase additional filters.

The Good

Purewaterclub POQ-4B-100 RO+DI Filtration Unit

Let’s take a quick look at the Purewaterclub POQ-4B-100 filter unit, which essentially comes with the same features as the POQ-4B-50, but produces twice the amount of filtered water per day.

First and second filtration stage need to be replaced every 6-12 months. The membrane can work for about 1-2 years depending on the amount of water you need. The deionizing filter needs to be replaced after 300-400 gallons of water.

As we are accustomed installing the device is pretty straightforward. You don’t need to be a professional plumber to figure out how to attach it to your kitchen or bathroom faucet.

The not so Good

Again you might need to visit your local hardware store in order to find the right adapter to attach the POQ-4B-100 system to your faucet.

Bottom Line

This is a solid product that can be used for gardening purposes or to fill your reef/fish tank.

Crystal Quest CQE-CT-00142 Countertop Reverse Osmosis Water Filter System

The Good

Crystal Quest CQE-CT-00142

Crystal Quest® has been manufacturing commercial water filtration and consumer products for more than 30 years. The company has established a number of brands that deliver their products to commercial and industrial customers worldwide. Crystal Quest headquarters are based in Kennesaw, Georgia.

The CQE-CT-00142 system features a 3-stage ro water filtration process that reduces silt, rust, dirt and other contaminants such as lead, copper and aluminum and delivers delicious drinking water.

The not so Good

Instructions for setting up the system are a bit vague. A clearer step-by-step guide would come in handy. In addition to that provided adapters might not fit on your faucet and customer support communication does not always go smoothly.

Bottom Line

The Crystal Quest CQE-CT-00142 costs about $170, which is a lot considering the fact that it is a countertop portable unit and is not 100% US made. Moreover it lacks clear installation instructions. We don’t think that this is the best countertop reverse osmosis system and there are better alternatives to choose from.
