Diwali is here. And as is the case every year, it brings with it lots of pollution. In fact, this year despite the ban on firecrackers, air pollution levels have risen by many times over the safety limit.
The disorders or diseases caused because of pollution is one of the most common problems occurring every year. A lot of people fall sick during and after Diwali. The worst affected are children, elderly, pets and those having allergy or issues like asthma.
While it is difficult to completely eliminate the pollution created by others, we can surely take measures that will protect us from few of the predicted problems. Apart from relying on medicines and altogether avoiding yourself from participating in the outdoor festivities, you can take some measures that will keep you safe from these problems.
Technology does come in handy in preventive measures. Of course, if the problem is severe, you have to consult with your family physician. Here is how you can protect yourself using certain gadgets and apps.
Air purifiers are used to purify the air inside a house, car, office or inside an industrial space. Most of the air purifiers filter out ultra-fine particles such as dust, pollen, floccules, hair and other particles up to the size of 0.3 micro-meter to 10 micro-meter. The size of the particles hanging in the air depends on the location and surroundings. Industrial places have larger particles as compared to the residential areas. So, while choosing an air purifier location and size of the place should be kept in mind.
The minimum efficiency reporting value (MERV) rating is used to measure the size of the particles filtered by an air-purifying device. It categorises ultra-fine particles according to their size. A filter with MERV rating more than 14 can filter particles up to 0.3 micro-meter and larger than it. Similarly, a MERV rating of 13 to 16 filters out particles of the size up to 1-0.3 micro-meters.
Most commonly found particles found in indoor places include virus, dust, smoke and pollen grains. These come under the MERV rating of less the 0.3 micro-meter. Bacteria, paint pigments come under 13-16 MERV rating that contains particles up-to 1-0.3 micro meter.
Other factors to be kept in mind before buying an air purifier include the Clean Air Delivery Rate (CADR), the area it is able to effectively purify, power consumption, noise produced and the longevity of the filter used in the air purifier. Since, smartphones are capable to control our home appliances, an app to control the air purifiers can also be desired from the product.
Based on the above factors, here are a few air purifiers you can invest in.

Air Masks work quite similar to the air purifiers. They too filter out fumes, vapor, gases and particles of different sizes depending on their capability and build quality. There are different types of face masks used in various situations but we will focus on the domestically used filters that can protect us from the outdoor pollution.
Air respirators are rated based on particle-resistance capabilities. The N95 and N99 rated masks are not able to filter out oil containing particles, whereas the P95 and P99 can protect you from oil containing particles. The 99 and 95 indicates the percentage of particles these masks are capable to filter.
The face masks come in different sizes and can be bought for children too. They should be bought based on the size of the particulate matter they are able to filter. It can be also used for outdoor use or while travelling to a polluted areas. These air masks come with a limited period of usage and should be thrown away after its dedicated time period for usage is over. One should also keep these masks inside a zipped package if it's not being used.

Before installing the app, one should check the compatibility and then use it for more accurate results. If things are getting too noisy beyond regular hours, you can use the decibel meter readings to let authorities know about the situation.

If you still want to experience crackers, then there are electronic ones which simulate the effect of crackers. These are not replacements for crackers, but can be surely used to reduce the pollution caused by crackers. They use electricity to produce noise and light. They produce no harmful gases and the level of noise produced by them is also minimal decreasing the chances of an hearing loss because of loud noise.
