The Home Master TMHP’s innovative design allows it to stand apart from its competitors. By using advanced technology, its 9-stage filtering system ensures 98% of contaminants are removed.

Reviewers talk about the easy installation of the Home Master, and how the taste is unsurpassed. That’s what added minerals can do for your water! On the other hand, some customers’ systems fell subject to leaks; although the excellent customer service from the provider is sure to help should you ever encounter any problems.

If you’re looking to upgrade the drinking water in your home, the Home Master TMHP is a must-buy. Say goodbye to ever buying bottled water again – you can go one better with this reverse osmosis system!

What really surprised us about the NU Aqua is its extraordinarily-long warranty. The system comes with a 5 year warranty, which is unprecedented for a product that falls into such a low price bracket.

This perfectly leads us into reviews of exemplary customer service. Where many budget products fail, the manufacturer of this system clearly cares about the experience of their customers.

Buyers who left reviews, however, also mention that this system’s performance is not as good as its more expensive competing products. Nevertheless, the overall performance is reported to be great.

Buyers noted the superior build quality of this product again and again. Whilst it boasts this high-quality manufacturing, that doesn’t mean installation needs to be tough.

This system provides great tasting water, with a 6-stage ultra safe filter system removing 99% of contaminants. One of the smaller products in this guide, it fits perfectly under kitchen sinks.

The Global Water RO-505 uses 5 filters in its filtration system. Whilst this may not be the most out of the products in this guide, each of them work tirelessly to provide you with clean water.

This reverse osmosis system doesn’t require any external power, and runs solely on water pressure. This makes it more ecologically friendly than one or two of its competitors. Plus, for the low price, its build quality really is excellent.

The RO-505 should be your chosen product if you’re looking for consistency, and reliability, from your reverse osmosis system.

The intelligence of this system is what really stands out to us. The manufacturers have recognised that, during its 6-stage layered filtration, the water loses some of its healthy minerals. So, rather than just leaving these out, they’ve developed a solution. An alkaline remineralization filter restores these minerals in order to produce a balanced alkalinity, therefore giving the water a more natural taste.

For the quality and advanced technology of this product, the price is fairly reasonable. However, some customers have raised an issue with lack of quality control due to leakages. This may be due to some confusion with teflon tape that seems to be prominent throughout reviews.

Many people want reverse osmosis systems to create fresher drinking water for their household. If this describes you, then this under-the-sink system should be your choice.

You may need to bear in mind that the UV system has been reported to break, so that tech support might come in handy if this is the case with your system.

Living in an area with low water pressure can be a hindrance when choosing your reverse osmosis system. Luckily, the iSpring 100GPD works with as little as 30PSI. So, if your home has a lower water pressure, this model would still work to excellent effect.

As one of the most reasonably-priced systems in this guide, the Whirlpool WHER25 only features a 3-stage filter system. Whilst it may not include the high number of filters its competitors do, it does make for easy maintenance whilst still giving you similar results. Filters are easy to replace, plus there’s less of them. This needs to be done every 6-12 months.

An additional incentive from the manufacturer, is that you receive a free auto shut-off valve and check valve if you’re using the system with a storage tank. All you have to do is let them know once you’ve placed your order.
