What are air purifiers?

An air purifier is a device that purifies the air in a room or a specific area.

It's like a silent helper that constantly removes dust, allergens, and other particles from the air around you. 🦠

The main purpose of an air purifier is to make the air we breathe cleaner and healthier.

These air purifiers come in all sizes, for small rooms like bedrooms or larger rooms like living rooms.

There are air purifiers available for every type of room.

How do air purifiers help combat smoke?

Have you ever wondered how to keep the air in your home free of smoke?

Smoke from cooking, forest fires, or cigarettes can make the air in your home unhealthy.

Let's take a look at how air purifiers can help with this problem.

What are the dangers of smoke in homes?

Have you ever thought about how safe the air is in your home, especially when there is smoke around?

Smoke in your home is more than just a bad smell – it's terrible for your health.

The smoke from cooking, cigarettes, or even barbecues in the house contains many chemicals and tiny particles.

These particles are so small that they can penetrate deep into your lungs. 🫁

If you breathe them in over a long period, they can cause breathing problems, aggravate asthma or even lead to severe illnesses such as chronic bronchitis.

It's not just your lungs that are affected.

Smoke can also irritate your eyes, nose and throat, which can be very uncomfortable.

This can be a big problem, especially for children, the elderly or people with health problems.

Smoke present in the home can have adverse effects on children and elderly individuals with health conditions.

In addition, the smoke particles don't just disappear but can stick to things like your sofa and curtains. 🛋️

They leave behind an odour and can later be released back into the air.

That's why using a smoke air purifier in your home is essential.

Using air purifiers to remove smoke from homes

Now that you know the risks of smoke in your home, let's look at how air purifiers can help eliminate it.

They draw in air from the environment and pass it through a series of filters.

These filters capture and remove pollutants such as dust, pollen, and smoke particles.

Smoke contains tiny particles and harmful gases, whether from cigarettes, cooking or fires.

The first line of defence in an air purifier is usually a pre-filter.

This pre-filter traps larger particles such as dust and pet hair.

It's beneficial when trapping the larger components of smoke, such as ash or soot.

After the pre-filter, the air is typically passed through a HEPA (High-Efficiency Particulate Air) filter.

HEPA filters are highly effective at capturing tiny particles.

They can trap 99.97 % of particles with a size of just 0.3 microns.

This includes microscopic particles in smoke, which pose a major health problem.

In addition to the HEPA filter, many air purifiers have activated carbon filters.

The activated carbon filter is the key to dealing with smoke.🌪️

It works through adsorption, in which gases and odours stick to the filter surface.

This filter is particularly good at removing the harmful chemicals and smells associated with smoke.

They use a combination of filters to capture a wide range of pollutants.

By understanding how air purifiers work, you can decide which air purifier is best for your needs.

Do air purifiers remove cigarette smoke?

When it comes to smoke from a cigarette, it's not just about the odour. 🚬

The smoke contains toxic particles and gases that can harm our health.

To counteract this, your choice of air purifier needs to be just right.

Most importantly, you choose an air purifier with a medical-grade HEPA filter and a heavy-duty activated carbon filter.

The filter is designed to capture very fine particles.

Tobacco smoke, with its tiny toxic particles, falls squarely into the category of pollutants that these filters are designed to trap.

They can capture particles as small as 0.3 microns, which covers most of the fine dust particles in smoke.

Then, there is the activated carbon filter. ⚫️

As already mentioned, these filters can absorb odours and gases thanks to their large surface area.

They "soak up" the harmful components of smoke from a cigarette, helping to purify the air and eliminate any remaining smoke odour.

Together, these filters do a great job of eliminating any smoke from a cigarette.

What are the best air purifiers for cigarette smoke removal?

Here are some of the best air purifiers for cigarette smoke removal in the UK.

What should you look for in an air purifier for smoke?

It's not always easy to find the best air purifier for smoke because there are many options.

Which features are most important? 🤔

We'll help you determine what you should look for in an air purifier to combat smoke effectively.

Types of particles filtered

Particles are really tiny, measured in microns, and this measurement is crucial when choosing an air purifier for smoke.

If you're dealing with smoke at home, you need an air purifier to handle the tiny particles.

These smoke particles are usually around 0.3 to 0.5 microns in size.

So, when choosing an air purifier, make sure it can filter out particles up to 2.5 microns in size to remove the smoke from your air.

Fortunately, the modern HEPA filters in air purifiers can filter out particles as small as 0.3 microns.

HEPA certified

An air purifier certified as 'True HEPA' has an efficiency of around 99.9995%.

You need this type of air purifier to combat smoke effectively.

But watch out for tricky advertising claims. 🎥

Some brands claim their air purifiers are 'HEPA-like' or 'True-HEPA', but these terms can be misleading.

Choosing an air purifier with an 'H13 medical-grade HEPA filter' is best.

This type of filter is more advanced and usually has a four-stage filtration system.

CADR

The Clean Air Delivery Rate (CADR) is an important indicator because it shows how well the air purifier can clean the air in a room, depending on the size of the room.

Graphic depicting clean air delivery rate of an air purifier.

Think of it as a score that tells you how well the air purifier does its job in different rooms.

It also helps you to find out how big a room the air purifier can clean.

Room Size

When looking for an air purifier to clear smoke, it's essential to consider the size of the room you want to use. 🏠

Let's say you have a room of 237 sq. ft.

Then, you should look for a large HEPA air purifier suitable for smokers with a CADR value of about 200m3/h.

This means that the air purifier is well suited to the size of your room and can clean the air effectively.

How can you find the right air purifier for smoke in your room?

To find the perfect air purifier for your room, you should pay attention to its functions and size.

An important consideration is that the air purifier's performance should match your room's size.

If you have a large room and choose an air purifier designed for smaller rooms, it may not clean the air as efficiently.

On the other hand, a small room does not need an oversized unit.

How do I find the right size HEPA air purifier for my room?

Choosing the right size HEPA air purifier for your space is crucial to its effectiveness.

Many brands offer a room size recommendation for their models.

However, it is advisable not to rely on this alone.

This is because these recommendations are based on the manufacturer's tests, which do not always reflect the diverse conditions in everyday life.

This is where the CADR comes into play.

It indicates how quickly the air purifier can remove pollutants such as smoke particles from the air. 💨

In a typical environment, the air circulates through the air purifier several times per hour.

You will achieve the best results if you base your decision on the room size and the CADR value specified by the manufacturer.

How loud are air purifiers?

When considering an air purifier, many people wonder about the noise it produces. 🔊

After all, the last thing you want is a device that disrupts your daily routine or sleep.

To find out how noisy these air purifiers are, we ran them longer with different settings.

Our tests showed that these devices are quiet and fit easily into your home.

To put it simply:

Low fan speed ▶ Low noise level

Increased fan speed ▶ Increased noise level

Even at higher settings for maximum filtering, the noise level only goes up to 50 dB.

This is about the noise of a normal conversation or a running shower. 🚿

The sound comes more from the air coming out of the vents than from the motor.

It's similar to the sound of a computer fan.

Do air purifiers for smoke really work - Conclusion

Let's conclude our discussion about air purifiers and their effectiveness against smoke.

The big question is, do these devices really work? Yes, they do help, but you must choose the right air purifier.

Air purifiers with HEPA filters can trap particles as small as 0.3 microns, making them very effective against the fine dust contained in smoke. 🦠

The carbon filters in these air purifiers are also good at removing odour and harmful gases from smoke, improving your air's smell.

But the air purifier will only work properly if it's the right size for your room.

You should always check the CADR rating to ensure it's powerful enough to clean the air in your room.

An air purifier that is too small won't do a good job in a large room.

Frequently asked questions

  • How much do air purifiers for pets cost in the UK?


    In the UK, air purifiers specifically designed for pets vary in price, largely depending on their features and brand. 💷

    Generally, you can find basic models starting at around £100

    Mid-range purifiers, which often come with more features, typically range between £250 to £400

    If you're eyeing high-end models with advanced technology, you could be looking at £500 and above

    We typically advise against going for the cheapest options. 

    This is because they often lack the necessary filter efficiency and fan strength to clear a room of allergens over time consistently. 🪭

  • What is the best filter for removing smoke from a cigarette?


    If you want to get rid of smoke from a cigarette in your home, a real HEPA air filter is the best option.

    These filters can capture the smallest particles and are ideal for ridding the air of smoke.

  • How often should I replace filters in air purifiers used mainly for smoke removal?


    If you use an air purifier mainly to remove smoke, you must change the filters every three to six months. 📆

    If the room is very smoky, e.g. due to regular cigarette smoking, you may need to change the filters more often.

    This is because the filters can fill up more quickly due to the smoke.
