Breathing. It is perhaps the thing we humans do the most in our lifetime. While the air in Singapore is usually in the good to moderate range, there are times when we suffer from poor air quality or high Pollutant Standards Index (PSI).

Who Needs an Air Purifier?
Almost everyone can benefit from having an air purifier. After all, who would complain about breathing in fresher and cleaner air? However, there are certain groups of people who would greatly benefit from an air purifier.
Allergies can be very irritating to deal with, especially when it affects you on a daily basis. Sneezing, wheezing, having a running nose, simply sucks. Having to reach for a tissue constantly can be very disruptive to our home and work lives. If you or a family member suffer from allergies, an air purifier could be the answer you are looking for. Higher grade air purifiers can help to lessen the number of allergens and pollutants in the air. This will likely lessen the instances of your allergies occurring.
Air purifiers are also recommended for people who are suffering from medical conditions. In these instances, you would require an air purifier that is medical-grade (True HEPA). These purifiers can also capture germs in the air and lower the chances of these germs spreading around the room. With so many potential health benefits, an air purifier is definitely a must-have in your home or office!
Things to Consider Before Buying an Air Purifier
True HEPA Filter
High-Efficiency Particulate Air (HEPA) is one of the main keywords that are used in the marketing dictionary for air purifiers. Why is this so? That is because the type of HEPA filter is the most important component to the effectiveness of any air purifier.
A True HEPA filter model is what you would want to get if you want to enjoy the true full benefits of an air purifier. To qualify as True HEPA, the filter has to effectively filter 99.97% of particles that are 0.3 microns, using the Dioctyl Phthalate Mil-STD-282 test. This technology was developed by the United States military in order to remove radioactive particles in the air. Currently, it is the highest type of air filtration technology available. True HEPA filters are utilized in places like hospitals’ operating rooms and Intensive Care Units (ICUs). Their job is to capture germs in the air, dry and kill them within the air purifier. This creates a sterile and clean environment.
There are some cons associated with an air purifier with a True HEPA filter. It will likely be noisier than a normal filter. This is because the engine within needs to work harder in order to push the air through the strong filter. Also, some models require you to change the filters when it is full so as to maintain optimal operations. However, the pros of a True HEPA clearly outweigh the cons. The air you breathe in will be the cleanest and freshest you and your family have ever had.
HEPA or HEPA Type Air Purifiers
Simply put, these type of filters are not as good as True HEPA. If a product is advertised as “HEPA”, “HEPA-like”, “HEPA Type”, “99% HEPA”, it is usually not using a True HEPA filter. Essentially, these filters utilize the same materials but do not fulfil the stringent requirements needed to be classified as True HEPA. These filters fail to pass the 99.97% D.O.P test. Typically, the effectiveness of such filters is between 25% to 95% compared to a True HEPA filter.
If you are going for an air purifier to enjoy fresh air, why not get the best and go for a True HEPA one? It won’t cost much more but will provide you with the best air that you can breathe.
Size of Your Office, Room or Home
Think of an air purifier like an air conditioner. If you turn on an air conditioner in one room, you won’t expect it to cool down the entire house. That is why we usually have an aircon unit for every individual room. Similarly, one air purifier is also effective in only one typical sized room if you want to enjoy its full benefits.
So, how do you calculate the effectiveness of an air purifier? WIthin the specifications of the air purifier, there should be one called the Clean Air Delivery Rate (CADR). This number reflects the amount of air that the purifier can filter in one minute. As a rule of thumb, you should get a purifier that has a CADR of ⅔ or more of the area that you want to place it in. However, there is usually no need to be so precise. Any competent air purifier will work effectively in the typical room sizes for Singapore.
Another tip is to place the air purifier close to the areas where you usually are. For example, in the bedroom, you will usually be on the bed. While if you’re at the office, you will be working at your desk. Therefore place it close to the bed and desk.
Ozone Purifiers, Yes or No?
No. We would strongly recommend that you not consider purifiers that emit ozone in order to clean the air. Instead of helping you breathe easier, ozone may be an irritant instead. It can lead to coughing, loss of breath and even pains in the chest. This is supported by the United States Environmental Protection Agency that states ozone does little to eliminate indoor air irritants but can instead be harmful and damage lung tissue.
Today, few air purifiers use ozone because of its negative effects. However, air ionizers or negative ion generators do provide a small amount of ozone from their purification processes. While the levels of ozone produced are usually within the recommended levels, we would still advise you to go for a HEPA air purifier.
Silence is Golden – Noise from the Air Purifier
We want to breathe fresh air. At the same time, we also want a quiet room for a night of peaceful sleep. We wouldn’t want a constant churning mechanical sound to interrupt our day or night. Unfortunately, there is some noise by-product from the air purifier. Most purifiers use mechanical filtration to push air against its filter to clear unwanted air particles which generates some amount of sound. In terms of measurement, we would recommend purchasing an air purifier that makes less than 40dB of sound while in operation.
What we found was that larger and more expensive air purifier produced lesser noise. This is because it does not need to run at maximum capacity in order to clean the room’s air. Instead, smaller units have to run at their neck-breaking speeds in order to achieve such effects which leads to their motors running loud. Most importantly, do look out for an air purifier with a low decibel rating so that you can enjoy your fresh air with a side of peace.
Costs of Operating an Air Purifier
Beyond the price of an air purifier, there are some variable costs that will be incurred in its operation. Firstly, an air purifier needs to be connected to an external power source. But do not worry, it costs a fraction compared to the operation of an air conditioner. We would estimate that it would cost between $50 to $300 per year if you use it for 24 hours a day, depending on the model. To reduce the electricity costs, look for models that carry the Energy Star qualification. They are more energy efficient and would reduce your electric bill by a decent amount.
Secondly, there are costs involved in replacing the HEPA filters in an air purifier. These need to be replaced about once a year or even more frequently if the air quality is bad. However, we have noticed that some models do come with a washable HEPA filter. You may want to consider these models if you want to reduce the annual running cost of the air purifier.
In total, it should cost an average of $100 to $200 per year. Definitely, a reasonable price to pay for clean air and good health!
Brands and Warranty
Go for the more established brands like Xiaomi, Dyson, Sharp, Novita, and Honeywell that are recommended in our buying guide. It is easier to find for spare parts and filter replacements instead of buying an entirely new air purifier if things fall apart.
A long warranty is also important. The best warranty period we have seen so far is 3 years which is considerably long for a consumer product. If possible, choose a model and brand that has at least a 2 year warranty period. Do not go for cheaper models with lower warranty periods as it may actually be more expensive in the long run if it breaks down.
