The most important criteria when buying a water filter

The most important criteria when buying a water filter

Water is the elixir of life - and we all want to make sure that the water we drink is as pure and healthy as possible. Maybe you've already asked yourself whether it makes sense to buy a water filter. Maybe you've even sifted through a flood of information that was more confusing than helpful. No wonder, because the market is full of different systems, promises and technical terms that are difficult to understand at first glance.

To make it easier for you to make the right decision, we will take a look at the most important criteria you should consider when buying a water filter. And don't worry, it's less complicated than it sounds at first!

The type of contaminants to be cleaned

The first and perhaps most important point: what do you want to remove from your water? Not every filter can filter out everything, so it is crucial to be clear about what you want from the filter.

Do you want to get rid of microplastics and chemical residues in particular? Or are you worried about bacteria and viruses? There are filters that are specifically designed for certain contaminants, so it's worth checking the water quality in your area or using a water analysis kit. In Germany, drinking water quality is generally very good, which is based on the strictest controls. A limescale filter, for example, would be worthwhile here, as even with the best water quality there can always be a certain amount of water hardness that could be reduced. Based on this information, you can decide whether you need a filter that removes heavy metals, chlorine, drug residues or microplastics.

type of filter

Not all water filters are the same. There are different types that work in different ways - and each has its advantages and disadvantages.

  • Activated carbon filters: These are the most common and suitable for everyday use in most households. They remove chlorine, odors, some pesticides and heavy metals - and often significantly improve the taste of the water.

  • Reverse osmosis filter: This option offers deep cleaning and removes almost everything from the water - even minerals. This is of course particularly thorough, but some people don't like the fact that useful minerals such as magnesium and calcium are also filtered out.

  • Ceramic filters: These are particularly good at trapping bacteria and other biological contaminants. They are a good choice if you live in an area with questionable water quality or travel a lot to regions with unsafe drinking water.

So it's worth taking a moment to think about what's most important to you - the choice of filter depends entirely on your individual needs. Bluaqua offers a wide range of high-quality filters, from carbonite water filters and limescale filters to nitrate filters .

The capacity of the filter and the filter change

Each water filter has a specific capacity, which means it needs to be changed after a certain amount of use or water volume. If you buy a filter with too small a capacity, you may find yourself having to change it much more often than you would like - and that will not only be inconvenient, but also more expensive.

An activated carbon filter that needs to be replaced every few months is not a big problem. But if you have or want to buy a filter that needs to process a lot of water on a regular basis - perhaps for a large family or for an office - you should make sure that the filter is durable and does not need to be replaced constantly. From my own experience, BWT water filter cartridges need to be changed frequently, even in a two-person household.

It is also practical if the filter indicates when it is time to change it. Nothing is more annoying than suddenly realizing that no fresh water has been in the glass for months because the filter was overdue!

Easy installation and handling

Not all of us are DIYers, and we don't have to be. But before you choose a water filter, you should make sure you can handle the installation - or whether you need someone to do it for you. Our team at Bluaqua is available to answer any questions and provide support, so feel free to contact us (please note the service hours). There are filters that simply connect to the faucet, while others need to be installed under the sink and require a little more effort.

Maintenance is also important. Some filter systems require regular maintenance or cleaning to function properly. If you don't feel like constantly changing or cleaning filters, look for a low-maintenance option.

costs and long-term nature

Of course, price also plays a role. This is not just about the purchase price, but also the running costs. Some filters may be cheaper, but they need to be changed more often, which adds up over time. Other systems are more expensive to buy, but last longer and require filter changes less often.

So think about the long-term costs before you decide on a model. An honest cost-benefit analysis will help you choose the right system - after all, your water filter should save you money in the long term and not constantly put a strain on your household budget.

environmental aspects

Another point to remember is the environmental aspect. If you choose a water filter, you are already doing something good by avoiding plastic bottles. But filters themselves also have an ecological footprint - especially if the filter cartridges have to be changed and thrown away frequently. So look for sustainable filter solutions or systems where the cartridges can be recycled or remanufactured.


Your water, your choice

Buying a water filter shouldn't be a stressful affair. If you know what you want from the filter and pay attention to the points mentioned above, you will easily find a system that suits your needs. Whether you are targeting microplastics, heavy metals or just want better water taste - there is certainly the right filter for you. So don't worry and take the time to find the perfect system. Your body and the environment will thank you!
