The filter also resists bacteria and mold growth [5], and with a 0.24-inch pressure drop, it maintains good airflow while capturing allergens [6].
"Nordic Pure premium A/C and furnace air filters improve air quality, reduce allergens, trap dust, and support health for cleaner air." – Nordic Pure [5]
A six-pack of 16×25×1-inch filters costs about $40 (around $7 per filter) [6], making it a budget-friendly choice compared to similar options.
With a 4.7-star average rating from 6,941 Amazon reviews [5], customers often praise its ability to handle pet allergens:
"With our dog always shedding, this filter has been a lifesaver for keeping pet dander and hair under control!" – Kelly P. [5]
For optimal performance, replace the filter every 60-90 days, as its efficiency decreases as particles build up. Available in multiple sizes, it fits most residential HVAC systems, and its pleated design increases surface area for better particle capture.

"Dust/pollen/smoke removal: How well models cleared air of fine clay dust and cigarette smoke. Ones that scored well for dust removal should perform comparably for pollen."
– Consumer Reports [7]
Its patented self-seal technology ensures no unfiltered air bypasses the filter, maximizing allergen capture without compromising airflow.
Compared to basic fiberglass and standard pleated filters, the Aprilaire 213 captures far more pollutants. It provides whole-house coverage without requiring extra fan power, making it both efficient and effective.
To replace the filter, follow these steps:
- Turn off your HVAC system.
- Remove the old filter and seal it in a bag.

To remove these irritants and have healthy air, an allergen air purifier is your best option." – Carrier [9]
The system boasts a 4.7/5 star rating [10]. While professional installation is recommended to maximize its benefits, the initial cost is offset by its whole-home coverage and advanced allergen removal, making it a smart long-term investment.
Choosing the Right Filter for Your Needs
Picking the right HVAC air filter for allergies depends on several factors, including the size of your household, whether you have pets, and the severity of allergy concerns.
For homes with just one occupant and no pets, a MERV 11–13 filter should work well and doesn’t need frequent changes. Larger households or those with pets might require filters with higher ratings, such as MERV 15 or HEPA filters, which typically need replacing every 20–45 days. If severe allergies are an issue, filters rated at MERV 15 or higher or HEPA systems are a better choice, with replacements needed about every 30 days to maintain performance [11].
Filter Types and Maintenance
- Disposable filters: These are easy to use and provide consistent results but need routine replacement.
- Washable filters: These are reusable and can reduce waste and costs but should be cleaned monthly.
For homes with pets, look for filters designed to capture extra dander and reduce odors. HEPA filters with activated carbon are particularly effective, trapping 99.97% of particles as small as 0.3 microns [12]. A good example is the Levoit Core 300, which features a "3-Stage Pet Allergy Filter" and offers strong performance at a reasonable price [13].
Maintenance Tips for Better Air Quality
Using the right filter is only part of the equation. Regular upkeep and a few simple habits can improve indoor air quality even further:
- Use a vacuum cleaner with a HEPA filter.
- Keep indoor humidity between 30% and 50%.
- Remove shoes and change clothes after being outdoors.
- Groom pets regularly to reduce shedding and dander.
These steps, combined with the right filter and consistent maintenance, can make a noticeable difference in your home’s air quality.
