Why choose a Eurovent Certified Company?

It’s really important to choose a Eurovent Certified Company for your air filters.

Now, more than ever, it’s vital to know that the filter you are buying will perform to the levels that the manufacturer is claiming.

Guarantee of performance

Eurovent certification is your guarantee of performance. There are many counterfeit filter medias available, which simply will not meet the standards claimed.

Indeed, many filter suppliers are not even able to test their filters to the latest standards and so are unable to guarantee filtration levels.

Tested air filters

We test our air filters to EN16890 and EN1822.

As the UK’s longest established air filter manufacturer, we pride ourselves in the levels of quality and service we offer.

Plus, we’re the only air filter manufacturer based in the UK that has an ISO16890 test facility too.

Tough energy efficiency standards for air filters

As the price of everything continues to rise and the demands for reducing CO2 emissions become more essential than ever, energy consumption related to air filters is our focus of attention.

The latest update to the Eurovent energy efficiency scheme came into effect in 2015.

With a new A+ grade and tougher limits, Eurovent 4/21 is good news for our customers and the industry alike.

Very best filters

Since the 4/11 programme was introduced in 2012, great strides have been taken in air filter technology. The products available today are now so efficient in their energy usage that the previous grading structure was no longer appropriate.

Eurovent 4/21 places a tougher limit on each grade and is structured to put a percentage of products into each category, so only the very best filters will achieve the highest classifications.

Eurovent energy efficiency classifications

Buyers of air filters will now find it a lot easier to find the right filter both in terms of energy efficiency and indoor air quality.

We’re a Eurovent Certified Company and have taken on board its new, objective energy efficiency classification are implementing it.

A+ is lowest energy consumption

All air filters can be graded from A+ to E: with A+ for the lowest energy consumption and E for the highest.

There are two key benefits for buyers and end-users:

• Selecting a higher-grade filter product will really mean you are choosing one of the most efficient options possible.
• The new classification encourages greater competition and product development, meaning better air filters with better performance. This tougher Eurovent 4/21 will result in air filters that offer even lower operating costs and energy consumption.

Eurovent 4/21 – energy consumption by filter grade (kWh)

The resulting effect of this re-structuring is that around 14% of all products will be downgraded from an A class – even those that fall just outside the new limit.

It should be remembered that the performance of these products has not deteriorated in any way; they still provide excellent energy efficiency. There is now simply more room for improvement.

It is also worth highlighting the difference in energy efficiencies between each filter grade. An A+ rated F7 filter could consume the same amount of energy as a B rated M6, for example.

So, it is crucial to choose a product according to what is required; not to over-specify the filter grade or select based upon purchase history.

The key is choosing the filter that will deliver the correct level of air cleanliness at the lowest possible energy consumption.

Working out the kWh number used in an air filter’s energy rating

• The filter is loaded with AC fine dust as specified in ISO 15957as L2in increments mtot and the pressure drop noted ∆P2
• A loading curve is then plotted on a graph
• Once the average pressure drop has been established, the equation below is used to calculate the Energy Rating in kWk. Calculation used in the new Energy Efficiency classification by Eurovent
• The kWh figure is purely a benchmark to compare one filter with another and should not be considered to be an actual consumption figure.

Breathe more easily with our help

It’s thought more than 5.5 million people worldwide die prematurely every year because of air pollution.

The effects of particulate matter (PM) on human health have been extensively studied.

The experts all agree that fine dust can be a serious health hazard, contributing to and, in some cases, even causing respiratory and cardiovascular diseases.

Smallest particles

A much less known fact is that research indicates that these smallest particles in the air are the most dangerous.

To provide a healthy and productive indoor air environment, this means that the focus should be put on filtering particles that are 1μm (micrometre) or smaller in diameter – particles also known as PM1 (Particulate Matter 1).

The human body has no protection against these very small particles.

Serious conditions

They enter our bodies through the respiratory system – we inhale them – and a significant number go deep into our lungs and continue into our blood stream.

It’s these PM1 particles that contribute to many serious conditions including heart attacks and lung cancer.


So where do these particles come from? The main culprits are the emission of small particles (1μm (micrometre) or smaller in diameter – particles also known as PM1 (Particulate Matter 1)) from power plants, factories, vehicle exhausts and from the burning of coal and wood.

The average person breathes in about 18,000 litres of air per day. Each litre contains some 70,000 visible and invisible particles.

That’s over a billion particles per day that our lungs must filter out.

In fact, the average home collects about 1lb of dust per week! A 3m x 3m carpet or rug will collect an average of about 4.5kgs of dust per year. Every day we eat 1kg of food, drink 2kg of fluid and breathe 25kg of air.

25 million particles

We can only see with human eyes 10% of what’s in our indoor air.

Indoor air is up to 50 times more polluted than outdoor air. We spend approximately 90% of our life indoors and every breath contains approximately 25million particles.
