Can pollen come through air conditioner

The air duct sometimes serves as a breeding space for molds, mildew, and some other bacteria when we fail to dislodge noticeable water deposits or buildup in them. Although with a proper filter in place, it should be technically impossible for them to make their way into our homes, when the filter becomes faulty, it will become easy.

Unfortunately, there are lots of things that can be airborne into your room through the air vent is as long as they are tiny enough to get through your AC’s air filter. One question I am usually frequently asked is “can pollen enter through the air conditioner” considering their small size. This article is my answer to that question and you are therefore enjoined to read to the very end to grasp the full detail.

Can Pollen come through the window air conditioner? 

Yes, pollen can come through the window air conditioner. When your air conditioner, especially the filter is not properly maintained, small particles present in the air like, mold, dust mites, pollutants, and pollen get trapped in them and then get airborne into your room when you switch on your AC unit. Therefore, you must ensure your unit always stays clean and also see to it that your filter is regularly replaced to improve the overall air quality of your room.

Do air conditioners filter pollen?

Yes, air conditioners help to filter out pollen. When you open your windows to allow ventilation, the air coming to your house comes in without any filtering mechanism that can ensure that the air is completely allergen or bacteria-free. And because of this, most allergists often recommend that homeowners install air conditioners to improve their air quality.

Most air conditioners come with HEPA-certified filters that are effective at filtering the air coming into your room through the air vent. The filter prevents the pollen and other allergens from coming to your room by trapping them in its pleated cloth or paper before transferring them to the duct.

How to keep pollen out of air condition

Many homes usually experience pollen invasions during spring. Although most of these people have a working HVAC system (useful equipment for air quality improvement), unfortunately, most of them hardly know to keep pollen and other allergens out. In this section, I will be discussing how you can use your AC unit to keep out pollen.

1. Get matching HEPA filters for your AC unit.

We have 4 different types of air filters, but unfortunately, not all these filters are capable of keeping out small spores and allergens from the air in circulation in your room. Therefore, it is recommended that you check the filter model you have in your AC unit to see if it is the required filter for your unit or you can ask your HVAC technician to do the verification for you during the weekly or monthly maintenance of your system.

However, these kinds of filters have downsides, they are usually thicker than the regular filters and therefore, contribute additional workload to your AC unit. Consequently, to avoid overworking your HVAC system, you should change them more often.

2. Trust your air conditioner

Many times, I have seen friends and neighbors who have a working HVAC system open their windows for ventilation. Anytime I ask them the reason for their action, their response is always the same, “nothing compares to fresh air and saving up on bills”. Although the second reason might be cogent, that’s not enough reason to make your house vulnerable to pollen and allergen invasion.

These allergens are so minute that they are capable of escaping through the mesh of your window no matter how effective they are. Therefore, during the peak of allergy seasons, you should always keep your window shut and allow your air conditioner provides all the indoor cooling you want. If you are so bothered by the cost of energy consumption, you can make use of a window unit as it can be run with minimal cost.

3. Keep your condenser away from pollen and other plants

You are likely to see more pollen around your house during spring as this is usually the time when flowers blossom. To ensure that you have clean air around your house, make sure the area around your condenser is clear of plants. Trim or cut any weed or plant growing around your condenser regularly to discourage their growth or you can make use of herbicides instead. You can also create a border for your unit with gravel or brick, just make sure the airflow of your unit is not blocked.
