The Importance of Air Purifiers for Expecting Mothers

For pregnant women, the risks associated with indoor air pollution are significant, including health complications such as asthma attacks and preeclampsia. Harvard University research has shown that purified air may have a direct effect on a baby’s cognitive performance, including attention span, memory, and problem-solving.

It is clear that reducing exposure to indoor air pollution should be a extremely high priority for expecting mothers. Filters and purifiers are two options that mothers can use to help protect their unborn children from airborne allergens.

Advantages of Utilizing an Air Purifier During Pregnancy

Reducing exposure to airborne pollutants has a number of benefits to pregnant women. These include reducing the risk of low birth weight, preventing respiratory issues, and minimizing the chances of preterm birth and developmental delays.

Understanding these benefits can help expecting mothers make informed decisions about why and how they can reduce their exposure to particulate pollution.

Reduced Risk of Low Birth Weight

Air pollution has been linked to low birth weight in newborns. Studies have shown that exposure to polluted air may disrupt a baby’s development, leading to low birth weight. Women in areas with high traffic or industrial activity, tend to give birth to infants with lower birth weights. Low birth weight increases the risk of developmental delays, chronic health issues, and even death after birth.

Air purifiers can reduce the amount of air pollution in the hone by filtering out harmful pollutants and creating a cleaner environment. This in turn helps avoid the risks associated with low birth weight.

Prevention of Respiratory Issues

Air purifiers can offer protection against respiratory issues for pregnant women by filtering out dangerous pollutants such as PM2.5, PM10, SO2, NO2, CO2, and more. These pollutants can lead to complications related to the eyes, brains, and lungs of their unborn children.

Air purifiers are also effective at reducing the risk of asthma attacks during pregnancy by filtering out various harmful pollutants. Experiencing breathing difficulties during pregnancy can put considerable strain on the womb, which may result in the baby developing asthma in the future.

Minimized Chances of Preterm Birth and Developmental Delays

NYU Langone’s Divion of Environmental Pediatrics found that exposure to air pollution can cause premature birth. Exposure to air pollution in pregnancy increases toxic chemicals in the blood and stresses the immune system. This weakens the placenta around the fetus and potentially leads to premature birth.

Roughly 3% of all premature births in the United States are due to air pollution. That is almost 16,000 babies every year that are born pre-term due to avoidable toxins in their environment.

Babies born prematurely may be more likely to experience slower mental development, dyslexia, ADHD, dyspraxia, visual-motor deficits, and mental disorders. By using an air purifier to improve indoor air quality, expecting mothers can reduce the chances of preterm birth and its accompanying danger.

Key Features to Consider When Choosing an Air Purifier for Pregnancy

There are several factors to keep in mind when picking choosing the best air purifiers for pregnancy. These include the type of filter, the size of the coverage area, the CADR rating, the noise level, and the energy efficiency. HEPA filters and activated charcoal or carbon filters are great choices, as they provide some of the highest levels of filtration available in the market.

The Clean Air Delivery Rate (CADR) rating is a measure how quickly the purifier can eliminate pollutants from a room. A higher CADR means pollutants are removed at a faster rate, making it more effective at improving indoor air quality.

Ensuring that the air purifier has a suitable filter type, coverage area, CADR rating, noise level, and energy efficiency will help create a safer and healthier environment for both mother and child during pregnancy.

Maintaining Your Air Purifier for Optimal Performance

Regular maintenance of an air purifier is essential to ensure that it is operating optimally and is able to effectively remove pollutants from the air. One important aspect of maintenance is cleaning the mesh pre-filter every 2-4 weeks, using a vacuum cleaner or a damp cloth to remove any dust or dirt that has accumulated on the filter.

The HEPA filter should be replaced every 6-12 months, depending on air quality and usage, following the instructions in the user manual for the respective air purifier. Additionally, it is important to regularly inspect the filter for any signs of damage or deterioration and to avoid placing the device in areas with high levels of dust or other contaminants.
