Introduction
An air purifier best at home is an appliance that eliminates contaminants from the air in a room to improve indoor air quality. According to the Environmental Protection Agency (EPA), no device can completely remove pollutants or substitute for ventilation with clean outdoor air but the best air purifiers can help to improve respiratory health.
The sheer size and weight of the Honeywell air purifier at home HPA300 were what struck us first during the setup. It weighs more than 17 pounds and it is designed for extra-large rooms. It has handles on either side which makes it easier to lift.
It has a multi-stage filtration process and comes with three HEPA filters as well as one odor-reducing pre-filter.
Operationally, it is one of the great air purifiers, features easy-touch controls that are simple to operate. Instead of having a low, medium, and high setting as with other purifiers we tested, the Honeywell air purifier has settings that vary based on one’s needs. It is also considered the best cheap air purifier for smoke.
Features
When tested, it was found that all settings worked exceptionally well for the Honeywell air purifier. The air purifier claims to be able to circulate all air in a large space five times per hour, which was valid. The filter also showed signs of effectively trapping dust and pet hair.
It has a two-step system: an outer carbon-activated filter designed to reduce odor, and three HEPA filters that screen particulate matter sized 0.3 microns or larger. The HEPA filters ensure the purifier can capture much smaller particles, like tobacco smoke or viruses. It has replaceable filters. It is recommended to change the pre-filter every 3 months, and the HEPA filter should be changed once a year.
Limitations
The major issue with this air purifier was the volume. It is larger than most rooms and is a challenging task to discretely place. Some people have experienced a rattling noise which they find unacceptable. The “Turbo” setting produces a loud noise which has proven to be too noisy.
The Philips AC1711 Smart Air Purifier offers advanced filtration with its HEPA and activated carbon filters, capturing up to 99.97% of airborne pollutants, including PM2.5 particles, allergens, and odors. It covers a room size of up to 441 sq. ft., making it ideal for medium to large rooms. The device is Wi-Fi enabled, allowing you to monitor and control air quality via a smartphone app. With a CADR of 300 m³/hr, it efficiently purifies the air, and its ultra-quiet operation at just 35 dB ensures undisturbed sleep.

When selecting an air purifier, first consider the indoor air quality needs. For air quality improvement, choose models with HEPA filters, or High-Efficiency Particulate Air filters, which eliminate 99% of common airborne allergens sized at 0.3 microns and larger. The airborne allergen includes pollen, dust, dust mites, mold spores, ragweed, and pet dander.
To choose the right size air purifier for your needs, consider the square footage of the room for which the air purifier is needed. If you have allergies then you should consider an air purifier’s air change per hour (ACH) rate.
ACH refers to the number of times an air purifier can filter the entire volume of air in the treatment space per hour. The rate of 4 air changes per hour ensures that the air purifier thoroughly cleans the air and filters out as many microscopic symptoms.
The placement of an air purifier is also an important aspect. Most purifiers have air intake either on the back or at the sides. Either way, it is advisable to leave some space on all sides of the air purifier for it to be able to efficiently take in the unclean air of the room and filter it. Never push the purifier against a wall.
An air purifier needs to be able to draw in and throw out at least a certain amount of air to fulfill the CADR (clean air delivery rates). The thumb rule with all air purifier purchases is simple- the more, the better.
Air pollution is harmful to your health and clean air is important for survival. But sometimes living in an area with pollution and feeling helpless because hiding away inside the air purifier forever is not an option. The Air Quality Index (AQI) was created by the Environmental Protection Agency which helps to monitor air quality to understand the impact it may have on our health.
HEPA filters are available to everyone as it’s simple and cheap to buy. What it does is, it draws suspended harmful particles, bacteria, viruses, smoke, gas, and likes by a fan at high speed through a dense mat inside it that has different sizes of gaps in it.
It’s like, only air will make it through the thick, multilayered mat, rest of almost everything like these harmful particles will get caught in the filter.
HEPA filter fibre catches airborne particulates in different ways. Majorly about 0.5 microns and above, particles less than 0.5 microns, and those below 0.1 microns. The largest size particles get caught by the filters when they impact it and get stuck to the fibre.
The second largest size particles, less than 0.5 microns, are picked up by blocking them when they try to flow around the fibres but come close enough to touch the fibres and get caught and stuck on them.
Ultra-small particles, below 0.1 microns, get bounced around and slowed by atoms and molecules present in the atmosphere inside the purifier, ultimately getting caught in a filter fibre.
Essentially, in this process, all particles get captured. According to HEPA standards, most of them mean 99.97 per cent capture.
