Plastic-Free Water Filters: Buying Guide

What Is a Plastic-Free Water Filter - And How Does It Work?

Plastic-free water filters do not have harmful plastic construction, be it in the product’s casing, the storage component, or the filter itself.

Such filters usually have a stainless steel or glass storage vessel with different filtration methods, like gravity-fed, activated carbon, or ion exchange filters, or reverse osmosis.

They remove microplastic particles along with other contaminants such as bacteria, viruses, and heavy metals present in water to ensure better drinking water.

Plastic-free water filters are available in three forms; plastic-free water filter pitchers, plastic-free tap water filters, and plastic-free water filter bottles.

As far as the design of a standard plastic-free water filter pitcher is concerned, it is pretty straightforward. The design consists of a reservoir and a filter component.

The filter component can use any material and mechanism for filtration, such as activated carbon, ion exchange, reverse osmosis, or multiple methods for a multi-stage filtration.

Water poured from the top of the reservoir passes through a replaceable filter for purification and is collected in the pitcher.

Depending on the construction of the pitcher, you may be able to store it in the fridge.

Tap water filters basically involve a filter that attaches to the tap. Water flows through the filter and is filtered.

Meanwhile, bottle water filters have a water filter attached to the cap that purifies water. 

Some futuristic water-filter bottle models use UV-C rays to sanitize the bottle and remove contaminants.

Why Buy a Plastic-Free Water Filter Over Other Kinds?

eco friendly water filter

There is no denying that plastic makes our lives incredibly easy due to its lightweight construction and versatility.

However, only a small amount of plastic is recycled, and a vast amount is dumped into water bodies. 

The chemical composition of plastic is also linked with congenital disabilities, cancer, etc.

Considering the adverse effects plastic has on people’s health and the environment, it is important to consume as little plastic as possible.

Plastic-free water filters don’t just reduce plastic footprint; they also filter out microplastics and other contaminants like heavy metals, pesticides, herbicides, etc., and improve the taste and smell of water.

What To Look for In Plastic-Free Water Filters

A few aspects to consider when buying plastic-free water filters include:

Contaminant Removal

Before you decide on a plastic-free water filter, it is important to know more about the water quality in your area. 

This will help you determine the contaminants present in the water, so you can buy a filter that effectively removes them.

If the water in your area doesn’t have arsenic pollution, it is a waste to buy a filter that effectively removes arsenic.

Instead, it is better to have a plastic-free filter that removes contaminants actually present in your water.

Purification Method

When it comes to plastic-free water filters, there are several filtration methods. 

This includes gravity-fed water filters, reverse osmosis, activated charcoal filters, and ion exchange filters.

Activated carbon filters are excellent for removing some of the more harmful contaminants like mercury, lead, and chlorine.

Ion exchange technology is best for softening water.

Reverse osmosis systems can remove chemicals like fluoride, chlorine, arsenic, and mercury, but they also remove beneficial minerals from the water.

Having an understanding of the filtration method will allow you to choose the most suitable option.

Filter lifespan

Every filter needs to be replaced after a certain amount of time.

To avoid replacing filters frequently without overusing worn-out filters, you should invest in good-quality filters with a long lifespan.

Check the filter rating prior to buying it to get an accurate idea of how many gallons of water the filter will purify in its lifetime. 


It is essential to take into consideration the construction and design of the water filter you opt for.

Choose a filtration system with sturdy and durable construction that can survive the occasional drop and not leak.

In the case of water filter pitchers, pay attention to the lid and spout design. Both the lid and spout should allow easy pouring and convenient filling.


Apart from sturdy construction and an innovative design, it is best to opt for a product backed by a good warranty service.

It shows the brand’s trust in its product and ensures that the water filter lasts a long time.

Plastic-free water filters come in different capacities. If you want a portable and sleek water filter pitcher or bottle, you will have to compromise on the capacity. Such filter pitchers will likely require frequent refilling.

However, if you don’t want to trade capacity for portability, opt for a larger pitcher that can store more water.

Pros and Cons



Cleaning and Maintenance

eco friendly water filter

Water filter cartridges wear out after a certain amount of time, after which you need to replace them. 

Some types of plastic-free sediment filters can be cleaned to restore filtration efficiency, but there’s no guarantee that the filter will be as effective as a new filter.

However, for efficient filtration, you need to regularly maintain your filtration system and replace worn-out filters instead of just cleaning them.

Also, clean the casing of the filter routinely. Wash the casing and reservoir of the water filter with mild soap and water.
