Air Filter Dollar General: Your Comprehensive Guide to Finding, Choosing, and Using Affordable Air Filters

2025-12-16

You can absolutely purchase air filters at Dollar General. This popular discount retailer offers a limited but practical selection of basic, affordable air filters suitable for routine replacement in standard home heating and cooling systems. For homeowners and renters looking for a convenient and low-cost option for a standard one-inch fiberglass or pleated filter, Dollar General can be a viable solution. However, it is critical to understand the limitations: the selection is narrow, often centered on common sizes like 16x20x1 or 20x20x1, and the available quality tiers are basic. Relying on Dollar General for specialized sizes, high-efficiency particulate air (HEPA) filters, or filters for sensitive air quality needs is not advisable. This guide will provide a complete, practical walkthrough of everything you need to know about buying and using air filters from Dollar General, ensuring you make an informed decision for your home's air quality and HVAC system health.

Understanding What Dollar General Sells

Dollar General stocks air filters under its own store-brand names, such as "EasyHome," and occasionally carries name brands like Filtrete by 3M in some locations. The inventory is designed for high turnover and basic needs. You will typically find two main types in the package aisles, often near cleaning supplies, light bulbs, or other home maintenance items.

The first and most common type is the standard fiberglass filter. This is the blue or white filter with a wiry mesh supported by a thin fiberglass grid. Its primary function is not to purify air for your health but to protect your HVAC system. It catches large particles like dust, lint, and hair, preventing them from clogging the furnace or air conditioner coils. These are the most affordable options, usually sold in single packs.

The second type you might find is a basic pleated filter. These have more surface area due to their folded, pleated design and are typically made from polyester or cotton paper. They capture a greater volume of small to medium-sized particles, including more dust, pollen, and mold spores. Pleated filters from Dollar General are a mid-tier option, offering a step up in air cleaning capability from fiberglass without the cost of advanced filtration media found at hardware stores.

You will not find specialty filters at Dollar General. This includes high-MERV rated filters, HEPA filters, carbon or charcoal filters for odors, heavy-duty allergen reduction filters, or media filters for whole-house systems. The store also does not typically carry less common sizes, such as those for window air conditioning units, many space heaters, or unusual furnace dimensions like 14x25x1 or 21.5x23.5x1.

How to Find Air Filters in Your Local Dollar General Store

The "home section" of Dollar General is usually organized by category, not by all home items in one place. Air filters are considered part of "Home Essentials" or "Home Cleaning." Start by looking in the aisle that holds furnace air filters, light bulbs, and batteries. If you don't see them there, check the aisle with cleaning supplies like mops, brooms, and laundry products. Sometimes, they are placed on a top shelf or an end cap.

It is important to note that inventory varies significantly from store to store based on location, season, and stock. A Dollar General in a suburban neighborhood with larger homes may carry a broader selection of sizes than a store in a downtown urban area. Your best strategy is to call the store ahead of your visit. Ask a store associate directly, "Do you currently have one-inch furnace air filters in stock, and do you have size [your specific size]?" This can save you a trip.

If you are comfortable with online shopping, you can use the Dollar General website or app. Use the "Find in Store" feature for a specific product. Enter your zip code to see real-time stock at locations near you. This tool is not always 100% accurate, but it provides a reliable starting point. Online, you may also see filters available for DG Pickup or DG Go, their contactless checkout and delivery services.

Choosing the Correct Air Filter Size and Type

Buying the wrong size filter is a common and costly mistake. A filter that is too small will allow unfiltered air to bypass it, dirtying your system and your home's air. A filter that is too large simply will not fit into the slot. Never force a filter into place.

The only way to be certain of your correct filter size is to check the existing filter in your system. Turn off your HVAC system at the thermostat for safety. Locate your filter slot. This is most commonly in the return air duct grille on a wall or ceiling, in the blower compartment of the furnace itself, or in a dedicated slot in the ductwork near the air handler. Carefully slide out the current filter. The dimensions are printed on the cardboard frame. It will read as three numbers: Length x Width x Depth, always in inches (e.g., 16x20x1, 20x25x1, 16x25x1). Write these numbers down. Also, note the direction of the airflow arrow printed on the frame; the new filter must be installed with the arrow pointing the same way.

If the old filter is too dirty to read, you can measure it yourself with a tape measure. Measure the exact length, width, and depth (thickness) of the filter frame. The most common depth is 1 inch, but some systems use 2-inch, 4-inch, or 5-inch filters. Dollar General almost exclusively carries 1-inch depth filters.

Once you have your size, match it exactly to the packages at Dollar General. Do not approximate. A 16x20x1 filter is not the same as a 16x25x1 filter. If Dollar General does not have your exact size, it is better to temporarily clean a reusable filter if you have one, or to purchase the correct size from a hardware store, rather than installing the wrong size.

Step-by-Step Guide to Installing Your New Air Filter

Proper installation is quick and ensures your system runs efficiently. Follow these steps:

System Off: Ensure your furnace or air conditioner is turned off. You can do this by setting the thermostat to the "off" position.
Locate Slot: Find the filter service door or return air grille. It may have a latch or clips, or it may simply be held in place by friction or screws.
Remove Old Filter: Open the compartment and carefully slide out the old filter. Take note of which direction the arrow on its frame was pointing (into the ductwork, toward the furnace/air handler).
Inspect and Clean: Before inserting the new filter, take a moment to look into the slot with a flashlight. Use a vacuum cleaner hose to gently remove any loose dust or debris from the area around the filter slot. Do not touch the internal coils or components.
Insert New Filter: Take your new Dollar General filter out of its plastic packaging. Find the airflow arrow on its cardboard frame. Point this arrow in the same direction as the old filter's arrow—toward the air handler/blower motor and away from the return duct. This direction is crucial; installing it backwards reduces efficiency and can damage the filter.
Secure: Gently slide the filter all the way into the slot. Make sure it sits flush and even. Close and secure the service door or grille.
System On: Turn your HVAC system back on at the thermostat.
Dispose: Place the old filter in a plastic bag to contain dust, and dispose of it in your outdoor trash bin.

The Pros and Cons of Buying Air Filters at Dollar General

Understanding the advantages and disadvantages will help you decide if this is the right source for your needs.

Pros:

Affordability: This is the primary benefit. Filters are priced very low, making it economical for frequent, routine changes.
Convenience: With thousands of locations, especially in rural and suburban areas, a Dollar General is often closer than a dedicated hardware store.
Basic Need Fulfillment: For standard sizes and basic system protection, their filters are perfectly adequate.
No-Frills Shopping: The transaction is quick and simple, with minimal choices to ponder.

Cons:

Extremely Limited Selection: Sizes and types are scarce. If you need a non-standard size or a higher-efficiency filter, you will not find it here.
Basic Quality: The filters are functional but use standard materials. They do not offer the advanced electrostatic or high-MERV media of more expensive brands.
Stock Inconsistency: You cannot rely on a specific size being in stock when you need it. Planning ahead is difficult.
Not for Air Quality Issues: If a household member has severe allergies, asthma, or other respiratory concerns, these filters are not a sufficient solution.

When to Choose a Dollar General Filter vs. a Hardware Store Filter

Your specific situation dictates the best choice.

Choose a Dollar General filter if:

You have a standard 1-inch filter slot and your exact common size (like 16x20x1, 20x20x1) is in stock.
Your main goal is basic HVAC system protection on a tight budget.
You need a filter immediately and a Dollar General is your closest option.
You change your filters very regularly (every 30-60 days) and prioritize low cost per change.

Choose a hardware, home improvement, or HVAC supply store filter if:

You need a non-standard filter size or depth (2-inch, 4-inch, etc.).
Your household has specific air quality needs, such as allergy reduction, pet dander control, or smoke/odor reduction.
You are looking for a filter with a higher MERV rating (between 11 and 13) for finer particle capture.
You prefer to buy in multi-packs for better long-term value and consistent supply.
You want to consult with knowledgeable staff about your specific system and needs.

Maintaining Your HVAC System with Regular Filter Changes

The single most important thing you can do for your furnace and air conditioner is to change the air filter regularly. A dirty filter is the root cause of many system failures and inefficiencies. It restricts airflow, causing the system's blower motor to work harder, which increases energy bills and can lead to overheating and premature failure. Restricted airflow from a clogged filter can also cause the evaporator coil in your air conditioner to freeze.

The standard recommendation is to check your filter every 30 days and change it at least every 90 days. However, this depends heavily on your household. Change it more often (every 30-60 days) if you have pets that shed, if there is high dust or construction in your area, if someone in the home has allergies, or during periods of heavy system use (summer and winter). A visual inspection is the best guide. Hold the filter up to a light source. If you cannot see light clearly through the pleated material, it is time for a change.

Mark your calendar or set a phone reminder for your next filter check. Buying an extra filter or two when you are at Dollar General ensures you have a replacement on hand when it's time. Consistent maintenance with a simple, affordable filter is far better for your system than sporadic changes with an expensive one.

Final Recommendations and Practical Tips

For most people using standard one-inch filters, Dollar General provides a practical, cost-effective source for a home maintenance essential. To ensure a successful experience, follow this final checklist:

Know Your Size: Always check the old filter first. Keep the size noted in your phone or on the furnace.
Call Ahead: Before making a special trip, call the store to confirm they have your size in stock.
Buy for Basics: Purchase Dollar General filters for routine protection, not for solving medical-grade air quality problems.
Change Regularly: Adhere to a strict schedule. Using a basic filter changed every 60 days is more effective than using a "premium" filter left in place for 9 months.
Have a Backup Plan: Recognize that Dollar General's stock is not guaranteed. Know the location of your nearest hardware store or be prepared to order online for a reliable supply of your exact size.

By understanding the product, your system's needs, and the store's limitations, you can confidently use Dollar General as part of a smart, budget-friendly home maintenance strategy. The goal is clean airflow and system protection, and a timely-changed basic filter from Dollar General accomplishes that core task effectively.
