Benefits of Replacing or Maintaining Your Filter

Helps Maintain Airflow

A post filter helps capture particles in the exhaust air path, supporting the vacuum's overall filtration system.

Offers Reusable Convenience

Because this filter is identified as washable polyester, following the correct cleaning instructions can help reduce unnecessary replacement frequency.

Supports Routine Vacuum Care

Regular filter inspection is a simple maintenance step that can help you identify buildup, wear, or damage before it affects performance.

Why Genuine OEM Parts Matter

Choosing the correct Riccar replacement filter helps maintain compatibility with your vacuum's intended filtration system.

  • Correct Fit: A model-compatible filter is designed for the designated filter location.

  • Filtration Support: The correct filter helps maintain the intended exhaust filtration arrangement.

  • Airflow Considerations: An unsuitable or poorly fitted filter may interfere with airflow.

  • Reliable Part Identification: Matching the part number helps reduce the risk of ordering an incompatible filter.

  • Dealer Support: Authorized Riccar Dealer Ace Vacuums can help you identify the appropriate replacement part for your model.

For dependable maintenance, verify your model number and select the correct Riccar filter rather than relying on appearance alone.

Replacement Guidance

Follow the manufacturer's instructions when cleaning or replacing your Riccar washable polyester filter.

  • Check the Filter Regularly: Inspect for visible dust buildup, damage, or deterioration.

  • Clean as Directed: Wash the filter only if the instructions for your specific model permit it.

  • Confirm Fitment: Verify that part #3621904300 matches your vacuum's model number.

Shipping, Return & Refund Policy

Shipping Policy

In-stock merchandise generally ships from our Leesburg, Virginia location within 3–5 business days. Processing time is separate from carrier transit time and is not a guaranteed delivery date. Weekends and holidays can affect timing. Special-order, backordered or unavailable items may take longer; contact us to confirm timing before purchase when a deadline matters.

Shipping options and charges are shown at checkout. After dispatch, follow the carrier's tracking updates. Weather, carrier delays, order verification and inventory confirmation may affect delivery. Inspect packages promptly and retain packaging if there is damage or an incorrect or missing item.

Returns and refunds

Eligible unused items have a 30-calendar-day return request window for refunds or exchanges, measured from delivery or in-store purchase. Return authorization is required. Final-sale exclusions, the 15% restocking fee for change-of-mind returns and shipping responsibilities are explained in our Return and Refund Policy. That policy is the governing source for return eligibility and fees.

For shipping or return help, email sales@acevacuums.com or call 703-997-9292.


30-Day Returns, Refunds and Exchanges

Updated September 27, 2026. Request a return for an eligible unused item within 30 calendar days of delivery (or purchase for items collected in store). Eligible returns may be refunded to the original payment method or exchanged, subject to availability. The same 30-day request window applies to both refunds and exchanges; there is no separate seven-day or 15-day refund deadline.

Eligibility and authorization

Items must be unused, clean, complete and in their original packaging with all accessories, manuals and proof of purchase. Contact sales@acevacuums.com or 703-997-9292 before sending anything back. Include your order number, item and reason for return. We will confirm eligibility, charges and return instructions. Unapproved or cash-on-delivery returns are not accepted.

Fees and shipping

For an approved change-of-mind return, a 15% restocking fee applies to the returned merchandise price. Original shipping charges are not refundable and the customer pays return shipping. These charges do not apply to an approved return caused by our shipping error or a damaged/defective item claim. Contact us first so we can arrange the appropriate remedy and shipping instructions. Do not assume a prepaid label is included.

Final-sale and excluded items

Air purifiers; discounted, clearance, trade-in, holiday-sale and price-matched purchases; gift cards; custom or special-order products; electrical parts; used or installed items; opened cleaning solutions; and used bags, filters, belts or other consumables are not eligible for change-of-mind returns. Other items clearly marked final sale at purchase are also excluded. An opened box alone does not disqualify an otherwise eligible unused, complete item, but consumables and cleaning solutions must remain unopened.

Damaged, defective, incorrect or missing items; recalls

Inspect your order promptly and contact us as soon as you discover a problem, with your order number and photos where helpful. Keep the packaging. Change-of-mind exclusions and deadlines do not remove applicable defect, warranty, recall or statutory rights. Warranty coverage requires evaluation under the manufacturer's terms; dealer status does not guarantee free repair. Recalled products must follow the manufacturer's recall process.

Refund timing and exchanges

After we receive and inspect the return, we will notify you of approval or the reason it cannot be accepted. Approved refunds are issued to the original payment method within 10 business days of approval; your bank may take additional time to post them. Contact us if more than 15 business days have passed since approval. Exchanges require authorization and replacement availability; any price difference and applicable charges will be explained before processing.

Applicable rights and earlier purchases

This policy applies to online and in-store purchases. We will honor more favorable written return terms provided with an earlier purchase. Applicable consumer rights remain unaffected. Where the European Union 14-day cancellation right applies, customers may cancel or return eligible orders within 14 days of receipt, subject to applicable legal exceptions, without giving a reason.
