Cold winters, hot summers, air pollution, the effects of all of these can be improved with the help of modern-day technology.

The market is flooded with a variety of air conditioners, air purifiers, and a host of similar products that are designed to alleviate the effects of air pollution and temperature changes.

If you live in a place with either very hot summers, extremely cold winters, high pollen counts, or polluted air, either an air conditioner or an air purifier is a must-have.

Options are very nice to have but sometimes the choice can confusion, more specifically which one of these do you need for your home or office?

In this guide we take an in-depth look at the differences between these air conditioning/purifying products helping to ensure you find the best option for your needs.

The Basics

An air purifier removes contaminated particles such as dust, pollen, mold spores, and pet dander from the air in order to improve air quality.

Air purifiers are commonly used for health reasons by individuals that struggle with asthma, allergies, and other respiratory diseases.

How Air Purifiers Work

Air purifiers work in two different ways. Active air purifiers work by filtering negatively charged ions into the air which causes the pollutants to stick to surrounding surfaces.

Meanwhile, passive air purifiers differ by using air filters to remove pollutants from the air, these air purifier filters are also known as HEPA filters.

Both types of air purifiers are effective but passive air purifiers are the preferred option since it permanently removes both small and larger particles such as dust mites, allergens, and air pollutants from the air by collecting it in the filters of the air purifier.

Air purifiers can either be stand-alone units or they can be incorporated into HVAC systems.

Air Conditioners Defined

An air conditioner is a machine that treats air in an enclosed area via a refrigeration cycle. Air is removed out of the room and replaced with either cooler or warmer air depending on the setting and temperature that the device is set to. Air conditioners are mainly used for comfort in areas that experience extreme temperatures.

How Air Conditioners Work

Air conditioners remove air from a room and the air is replaced with conditioned (warm or cold) air. Air conditioners all work on the same principle but they are available in different shapes and sizes.

Window Air Conditioners

Window air conditioners units are normally found in a window or in an exterior hole in the wall. Window air conditioners have limited cooling capacity due to its size and static location, these low-cost units, however, are great for individual rooms or small apartments that don’t have a central HVAC system.

Air Source Heat Pumps

Air source heat pumps are a cost-effective air conditioning option for homes with ductwork. Air source heat pumps use electricity to move warm and cold air around throughout your home. In winter the heat pump brings concentrated warm outdoor air into the house from outside and during the summer months, it concentrates warm indoor air in your house and dumps it outside.

These energy-efficient systems are best suited for areas with mild temperatures and works very well in Southern California, but may not fare so well in Minnesota.

Central Air Conditioners

Central air conditioning systems consist of two units, the condensing unit (outside the home) and the evaporative unit (inside the home). These luxury units deliver cool air in every room within a house simultaneously and the majority of modern homes in the US feature these systems.

Ductless Air Conditioners

Ductless air conditioners are also known as split system air conditioners. These systems are ideal for homes without ductwork and offer a more permanent solution than window air conditioners. Ductless air conditioners feature one unit on the inside of the home and one unit on the outside of the home, the two units are connected by refrigerant tubing pipes.

These systems normally only cool one room at a time but depending on room size more advanced systems are able to cool multiple rooms simultaneously.

Portable Air Conditioners

Portable air conditioners can be moved in and out of a room as you please. These air conditioners feature a hose that discharges hot air out through an exterior window. Portable air conditioners can be noisy but they are great temporary cooling solutions.

Do air conditioners purify the air?

Air conditioners aren’t designed to purify indoor air but they do feature filters that filter some pollutants to improve indoor air quality.

The Key Differences Between Air Purifiers and Air Conditioners

It’s all in the name, air purifiers purify the air and air conditioners condition (either heat up or cool down) the air. Air purifiers remove pollutants from the air meaning individuals that suffer from asthma, allergies or other respiratory diseases can benefit greatly by installing an air purification system in their home.

Air purifiers are also a great addition to your bedroom to ensure that you get a good night’s sleep while breathing in clean pollution-free air.

Air conditioners are different from air purifiers, and while air conditioners do purify the air to some extent their main function is to condition the air to change temperature. Air conditioners are mainly designed for geographical locations that experience either extremely hot or cold temperatures depending on the season.

Air conditioners are available in many different shapes and sizes to suit your heating/cooling needs. Central air conditioners are built into modern homes and these high-end luxury systems are very nice to have. It’s not the end of the world If you don’t have the luxury of a central air conditioning system, portable air conditioners, and ductless air conditioners are very effective alternatives.

What About Dehumidifiers?

Humidifiers differ because they add water to the air in order to increase the humidity within a room.

Humidifiers are a welcome addition in areas with dry desert air. A variety of health-related issues are aggravated by dry air including allergies and asthma.

In addition to providing relief for allergy and asthma-related issues humidity also ensures that your skin doesn’t dry out.

Humidifiers are available as stand-alone devices or they can be connected to your home’s HVAC system.
