Best Indoor Air Quality Monitor

While we all look forward to the warmer days and lighter nights of spring, this time of year means the arrival of allergy season for many of us.

Sneezing, coughing, streaming eyes, and a blocked nose can cause untold misery for many hundreds of thousands of people each year, so the quality of your indoor air is an essential factor for so many sufferers of seasonal allergies.

Even if you don’t react to pollen, there can be many other airborne allergens that can reduce your indoor air quality and make it unhealthy to breathe. Air pollution from traffic fumes, dust, mould spores and pet dander are other common allergens that many thousands of people struggle to deal with all year round.

Your indoor air quality relates to your comfort and health, so making sure that you maintain healthy air circulation around your home or office can help reduce symptoms similar to a head cold or another viral disease.

It can be hard to determine whether you have contracted a cold or if it is the irritating allergens in the air that are causing your symptoms. If you have an indoor air purifying system and notice that your symptoms fade while indoors but worsen when you go outside, you will know the cause.

It can help to monitor your indoor air quality to ensure you remain comfortable and symptom-free while spending time in your home or office. Our indoor air quality monitor reviews will help you achieve this.

Air quality monitor FAQs:

How to measure indoor air quality

The best way to test your air quality is to invest in an air quality monitor that tests for many indications of poor air quality, such as CO2 levels and particles in the air.

What is indoor air pollution?

Indoor air pollution can be a number of things floating in the air inside your home or workplace, such as dust, pollen, dirt or chemical particles, for example, carbon monoxide, nitrogen oxide, sulphur dioxide, or gases that could be harmful to breathe in.

High levels of indoor air pollution have been linked to diseases like asthma, COPD and lung cancer, and increased risk of heart disease and stroke. 

How to reduce indoor air pollution

The easiest way to reduce indoor air pollution levels is to open your windows. However, this is only effective if the outdoor air quality is good. Letting in more pollen or damp air may not be good if you have asthma.

You can do other things, including reducing pet dander by bathing your pets and washing their bedding frequently. Use electric air purifiers and AC filters. Fit an exhaust fan in the kitchen to remove cooking fumes. An extractor fan in the bathroom will help remove steam and damp air that can encourage mould and mildew growth.
