Best Quiet Air Purifier: Questions and Answers
For any household appliance bound to take some space in your interior, silence is a definitive concern. In our mind, a quiet air purifier is our number 2 concern (after efficiency of air purification) in all of our tests.
Under how many decibels is an air purifier considered silent?
Any type of air treatment machine will release a “white” noise, a consequence of the micro-vibrations happening between the air released or engulfed, and the unit material.
Now, air purifiers vary in quietness. You can expect a noise level below 55 dB to be acceptable for an air purifier. Below 50 dB, you have an exceptionally silent air purifying unit.
Where should I place my quiet air purifier?
Most air purifiers lack the capability to clean air in multiple rooms. As such, you should set the unit in the room where you spend most of the time. Such a space can be a bedroom, living room or the home office. Some models have caster wheels, and you can, therefore, move them from one room to another with ease. You should avoid covering your unit or positioning it next to items that can obstruct free flow of air.
For large rooms, you should put the unit at the center to make sure that it purifies the entire area. Also, place the appliance at least four feet from the wall for common rooms to ensure that there is enough air circulation.
What are the indicators of air contamination?
If you experience difficulties in breathing after moving to a new house, this can be an indicator of air pollution. Consult your family physician to establish whether the breathing problems are as a result of air contamination. The presence of odors, dust and pet dander, are other indicators of air pollution in your house.
You need to establish the source of pollution first so as to determine the most suitable air purifier for your house.
What are HEPA Filters and how effective are they in cleaning the air?
HEPA filtration; which stands for High-Efficiency Particulate Air filtration, is a filter based air clean mechanism that has a capability to remove 99.97% of contaminants from the air as long they are 0.3 microns or larger. These filters can remove pollen, dust mite residues, and pet dander particles from the air.
Pre-filters are used together with the HEPA filters. They trap large particles such as fur, insects, and so on. The pre-filters also help to shield HEPA filters.
Carbon filters contain activated carbon granules which remove chemicals and odors from the air in your room. These filters can deal with contamination arising from fireplace fumes, cigarette smoke, paint fumes, pet odors and carpet glues.
Will a quiet air purifier cure my asthma problem?
No. These units do not cure asthma or other diseases related to air contamination. The system just cleans the air which reduces your chances of contracting such illnesses and visits to the doctor. The air purifier also removes allergens which make the environment more conducive to those people who are allergic to dust, fumes and pet fur and dander. It is advisable to select a unit that uses HEPA filtration because its cleaning capability is higher as compared to other mechanisms.
Asthma patients should also avoid systems that emit ozone from ionizing technology. These emissions can affect the air quality and aggravate a respiratory problem.
What is CFM?
Cubic feet per minute (CFM) is a measure of the amount of air that passes through an air purification system in one minute. Models with higher CFM have a greater capability of cleaning the air in a given space. The factors that affect the CFM include furniture in the room, fan speeds, and air flow.
What is ACH and how does it affect the quality of air in my room?
Air Changes per Hour, abbreviated as ACH, is commonly used as a measure of capacity of an air purifier to clean the air. If the system has an ACH of 4, it means that it changes the air four times per hour. Most manufacturers recommend systems with ratings of either 5 or 6. Asthmatic people are usually advised to use air purifiers with high ratings.
Will a quiet air purifier remove all types of pollutants from my room?
Air purifiers that are based on HEPA filtration are an excellent option for removing microscopic particles such as pet dander, allergens, and pollen. If you have poor indoor air quality as a result of chemicals and odors, you should use a unit that has carbonated filters.
Is a quiet air purifier expensive to run in terms of power consumption?
The power consumed by an air purifier for a given period of time varies from one model to another. The total power consumed by a quiet air purifier is mainly determined by the rating of the appliance and the number of hours that it operates. Appliances that have the Energy-Star rating are optimized to consume less minimum power.
Should I run my system for the whole day?
For optimal results, operate the unit continuously. Most of the models in the market allow you to select the cleaning speed which affects the noise level and energy consumption. When you are away from home, choose low fan speed and use the medium setting while at home.
After how long should I change or clean the filters?
Some models come with permanent filters while others have replaceable and washable filters. You should clean the filters regularly depending on the level of usage and air contamination. In the case of replaceable filters, you should change them after six to eight months as specified by the manufacturer. Some quiet air purifiers have an indicator light that alerts you to either change or clean the filters.
What is CADR rating and how does it affect the cleaning capacity?
CADR, in full, Clean Air Delivery Rate is a measure of the amount of clean air that the unit delivers to a given room in cubic feet every minute. The CADR rating is among the key factors that one should consider when selecting a quiet air purifier.
Will a filterless system purify my entire house?
Most filterless units are incapable of capturing minute airborne particles. An air purifier that blends HEPA filtration and carbon filtration can capture microscopic particles found in molds, chemicals, and smoke. Filter-less air purifiers are usually cheaper as compared to filter-based units.
How many quiet air purifiers do I need to clean my entire home?
The number of units that a space requires mainly depends on the number of rooms in the house, the size of the rooms, furniture, and level of air contamination. When selecting a position for your air purifier, your first priority should be spaces with high traffic such as your living room.
