Portable air purifiers have become a market trend with the latest technology other than using old bigger-size home air purifiers.
With its small size, low price tag, and limited range of air purification, most of the community is comfortable with portable air purifiers for their car purification, office lobby cleaning, and even as a desk decorating ointment.
Before Select a portable Air Purifiers
You need to consider several features of a portable air purifier before making a proper selection. These should consider before selecting most kinds of air purifiers.
1. CADR Rating
CADR rating stands for Clean Air Delivery Rate. It is considered a direct measurement of the air purifier’s efficiency.
It measures under the unit of CFM -cubic feet per minute, which says how much air volume goes through the filter in minutes while doing the filtration task. Mainly we consider air pollutants of smoke, pollen, and dust for this removal process.
The CADR ratings were developed by the Association of Home Appliance Manufacturers (AHAM) to give a general idea about the capability of air purifiers which consumers can quickly identify, manufacturers and authorities.
Generally higher CADR value is suitable for good purification. So is it okay to buy the highest CADR valued purifier in the market?
Actually, things are not going that way. Most higher CADR air purifiers are designed for high air polluted atmospheres.
Eventually, it needs a high-performance machine. Because of that, they are creating high noise and coming with a higher price tag. CADR value should choose concerning your air purifier place location.
If it is a portable air purifier, this value is relatively low. Because it focuses on low range atmosphere and low energy requirements.
The size of an air purifier is not a significant key factor when selecting a home or industrial place. However, it is a critical factor in a limited location like a car, dorm, or desk.
Most portable air purifiers are designed in small cylindrical shapes and sizes, which are capable of fitting into car cup holders.
However, some of them are not. Even though some of the air purifiers have a better performance, they are quite hard to handle and place.
Quiet air purifiers are commonly seen in the market because they are a market attraction factor, and people are unaware of the noise level behavior.
Most excellent air purifiers need to mention their operation noise in both day and night times in decibel values. There are critical reasons behind air purifiers’ noise levels.
- Frequency of the number of waves emitted in a certain period by the purifier
- Filters lifetime and amount of impurities clogged inside.
- Noise depends on the amount of energy consumed or the size of the air purifier machine
- Environment Parameters can change the Noise transmission through the atmosphere
Every person does not become sensitive to all the hearing frequencies. Here is common regions person reacts.
Typically, if the decibel region is below 40 dB of the purifier, it is considered perfect for our consumption.
Usually, portable air purifiers in the market have a minor noise level compared to others.
Because of its lower machinery capacity, small filters, and low battery, practically, they cannot create a massive disturbance.
4. Energy Star value
Regular air purifiers are designed to run 24 hours, seven days a week. Nevertheless, portable air purifiers are not operative like that. They usually work for a limited period.
According to ENERGY STAR certification
“Room air purifiers are over 25% more energy-efficient than standard models, saving consumers about 120 kWh/year and 15 USD annually on utility bills. These savings could add up to 120USD over its lifetime!”
Before selecting an air purifier, check the ENERGY STAR certification. Most of the branded products follow that.
5. Filter Configuration
There are several settings of filter configurations in the air purifiers. Most advanced air purifiers maintain more than three filters inside. Besides that, dual single filtration systems are pretty familiar in the market at low price scales.
One of the most often used filter setups is,
- Washable Pre-filter + Activated Carbon Filter + a HEPA filter
- Washable Pre-filter + HEPA Filter
Also, there is the following kind of filter sets too.
- Washable Pre-filter + Honeycomb-Structured Carbon Filter + Medical-grade H13 HEPA Filter
- Washable Pre-filter + Deodorization filter+ Green True HEPA filter
Apart from these, there are several kinds of filtration setups. They mainly depend on the air contaminants that we are required to filter.
