Sneezing and coughingwatery red eyes and difficulty breathing? Allergies could have you in a choke hold (literally) this spring. Experts say that the U.S. will see even earlier spring leaves and flowersand a longer growing season that will release extra pollen earlier this spring. That's bad news for our spring allergy sufferers.

In the U.S.air quality has changed dramatically due to climate change and extreme heatpollution (from vehicle exhaust to industrial emissions)smoke from wildfirespollen and more. The expected wildfire potential is also increasing following below average February precipitation levels in the many areas of the U.S.

Changing climate has caused shifts in precipitation patternsmore frost-free dayswarmer air temperatures and more carbon dioxide (CO2) in the atmosphereaccording to the U.S. Department of Health and Human Services. Due to these changesthe seasonal outcome means higher pollen concentrations with earlier (and longer) pollen seasons.

The solution? A properly selected air purifier with proven pollen removal capabilities. Not all units deliver on their promisesso we'll be focusing on models with verified CADR ratings and performance data. In this guidewe cover how pollen can impact your healthand a few important tips to keep in mind when picking out the best home air purifier to improve your indoor air quality.

What Is A Pollen Allergy?

An allergy is when the body overreacts to a trigger that is usually inhaledor may enter through the nose or eyes. Common allergy examples include hay fever (allergic rhinitis)asthmaeczema or food allergies.

Symptoms of allergies include face swellingsneezingrunny nosewatery or itchy eyesskin rash or breathing problems. In severe casesa major allergic reaction may cause anaphylaxiswhich can be life-threatening.

Can Pollen Cause Respiratory Problems?

Yespollen can cause respiratory problems. If you’ve done any reading on HEPA filters and air purifiersyou may have come across the term “PM2.5”which stands for particulate matter 2.5 microns or smaller.

Particulate matter is the term for particles like pollendustdirtsootsmoke and liquid droplets found in the air.

Particles less than 2.5 microns are referred to as “fine” inhalable particlesaccording to the EPAand can pose health risks if they lodge into the lungs. Measuring less than 5% of the width of a human hairit can cause a range of health effects from minor eyethroat and lung irritationto asthma attacksworsening heart disease and other chronic conditions.

The Worst Time Of Year For Pollen

Tree pollen allergies peak in early springgrass pollen by late spring and early summerand weed pollen (including ragweed) by late summer and fall. Season length and timing varies by the weather and geographic location.

Pollen seasons in the U.S.

• February to April: Trees
• April to early June: Grasses
• August to first hard frost: Weeds

Common Pollen Producers

Tree pollen allergies in the spring and summer are caused largely by plants spreading pollen by wind. While some trees produce that fine yellow dust you’re constantly cleaning off your car and windowsother trees can produce pollen that can’t be seen. Trees that cause the most common allergy symptoms may include ashaspenbirchcedarcottonwoodelmmapleoakpoplar and willow.

Grasses that trigger allergy symptoms include bermudafescueorchardrye and timothy. Grass allergies can lead to certain foods triggering the same symptomscalled oral allergy syndromebecause grass pollen is similar to the protein in some fruitsvegetables and nuts.

Weed pollenespecially ragweedis especially difficult for allergy sufferers. Weed pollen typically appears in late summerand common types may include mugwortpigweedsagebrush and tumbleweed.

Picking An Air Purifier To Help Combat Allergies

There’s a few important tips when it comes to picking the best air purifier to remove pollensmoke and dust. Not all home air purifiers are created equalso it’s critical to do your research on some of the key claims.

Here are a few filtering options to keep in mind while shopping for an air purifier:

1. HEPA filters
2. CADR rating
3. Carbon filters

1. HEPA filters

A HEPA filter (also known as a “high efficiency particulate air” filter) should theoretically be able to remove at least 99.97% of dustpollenmoldbacteria and other particles with a size of 0.3 microns.

A MERV rating (“minimum efficiency reporting values”) will also help determine a filter’s ability to capture particles between 0.3 and 10 microns. The higher the MERV ratingthe better the filter is at trapping specific types of particlesaccording to the EPA.

The efficiency percentage of an air filter for particles between 0.3 to 1.0 microns at a MERV rating of 14 or 16.

2. CADR

Clean Air Delivery Rate (CADR) is a standard measurement created by AHAM that measures how much air (the volume of air) that an air purifier can filter in a given amount of time. It’s measured in cubic feet per minute (CFM)and will have separate scores for tobacco smokepollen and dust. The higher the numberthe faster the unit filters the air.

To determine the best CADR rating for your roomstart by measuring the dimension of the room’s area. For example10 ft. x 12 ft. would be 120 sq. ft.

The AHAM recommends a CADR rating of at least two-thirds of the room’s area. So for a 120 sq. ft. roomthe minimum CADR rating would be 80. A CADR rating of 200 for pollenfor examplemeans it can remove pollen particles from a room of 200 sq. ft. at a rate of 200 cubic feet per minute (CFM).

3. Activated carbon filters

Activated carbon filters can absorb and remove odorsgasesVOCs (volatile organic compounds that come from cleaning productscarpetsair freshenersand combustion chemicals)and pollutants like tobacco smokedustand pollen from the air. Consider activated carbon filters to be your odor eliminators.

Activated carbon filters will need to be changed out eventually after use. The average lift span is anywhere between three to six months depending on the concentration of pollutants and humidity levels in your home.

How Long Does It Take An Air Purifier To Clean Indoor Air?

According to one sourcea general rule of thumb for air purifiers is that small rooms take two to four hoursmid-size rooms between four to eight hoursand large open spaces eight or more hours for complete air filtration.
