Factors to Consider When Buying A countertop Reverse Osmosis System

1. Size

We've looked at several fantastic countertop systems. Now, the critical part is knowing which one is suitable for your current available space. You don't want a large reverse-osmosis system that will clutter your place further.

Therefore, if you don't have enough space on your countertop, you can go with an under-counter reverse-osmosis system that will fit nicely under your sink. Before you make your order, measure the available space against your system's size so that you won't have to send it back.

2. Budget

Ask yourself how much you are willing to spend comfortably. This will give you a rough idea of what price range your reverse-osmosis filter will fall under. The standard price range is between $250-$500, such as the great options we've outlined for you above.

You'll find some more expensive options that boast more stages of filtration, an ability to filter larger quantities of water, and some cool extra features such as autoflash. Some can even add more nutrients back into your driving water.

If you have a large family or prefer the extra features that come with the high-end options, don't shy away from choosing them if your pocket can allow. Ensure that you don't choose a cheap reverse-osmosis filter made of cheap materials that will leave you having to replace it in no time.

3. Effectiveness

We've mentioned above how many stages each system has. Therefore, choosing a product with at least four stages will have you drinking water that is pure and has a great taste. However, note that the choice in the number of stages you want your filter to have depends on the state of tap water you're starting with.

If you feel like you need a system with more than four stages, you can invest in a system with five or even six filters.

4. Amount of Water

We've mentioned above that one of the perks of having a high-end filter is that you get to filter large quantities of water at a go. Several reverse osmosis water filters indicate how many gallons a day they can handle. Therefore, as you are checking for the system you want, ensure that you consider the capacity.

Nonetheless, most standard sizes range between 50-100 gallons. A 50-gallon system should be enough for a relatively small household.

5. Waste Water

The one downside to countertop RO systems and other reverse osmosis filters is that they create a lot of wastewater. However, some recover 5-15% of the water they filter. If you don't like seeing water go to waste, investing in a reverse-osmosis system that reduces water waste through repurposing is a good idea.

These zero-waste systems repurpose the wastewater to dishwashing and laundry, among others. However, note that the wastewater contains more contaminants and chemicals.

6. Lifespan

We understand that you want value for your money, and that's why we curated a list of brands known for their high-quality products. The last thing you want is to choose a product that will serve you for a few months then break down.

The best part is that many reverse-osmosis systems come with warranties. In some cases, you'll find that they come with limited lifetime warranties. If you want to be sure that the product is rock-solid, you can opt for filtration systems that offer a solid warranty.

Conclusion

We hope that you've found this reverse osmosis filtration review helpful, and you can now make an informed decision on which portable reverse osmosis system you want.
